The Gibson SG - A Most Unique Guitar

When I was 13 years old, I would arrive for my guitar lesson about an hour early at Dodds Music. That way I could check out all the new guitars. I can recall when the store had this beautiful guitar hanging in a display case.

1961 Gibson SG Custom
It was a Gibson SG Custom with an ivory finish, three gold-plated pickups and a gold-plated side-to-side vibrato. The neck was ebony with large block fret markers and the headstock had large white pegheads. The emblem at the base of the neck proclaimed it to be a “Les Paul.” What a beauty.

In my opinion, the SG shape has to be one of the most original guitar designs. It was shaped like no other guitar at the time. Gibson gave it the designation SG which stood for solid guitar.

Believe it or not, the SG was introduced in 1961 as a replacement for the single cutaway Les Paul Standard.

Sales of Les Pauls were on the wane and Gibson wanted a new flashy guitar that would attract players.

I have been unable to determine who actually designed the SG. Gibson attributes the SG design to Ted McCarty. He was head of the company at the time and is credited with designing a number of Gibson's other instruments.

There are some folks that believe the SG's body started out as a Les Paul body slab which a designer cut with an extra cutaway. To me the SG looks like a totally different guitar that is very unique and original. The SG is very different in size and shape from the single cutaway Les Paul.

What we  know for certain is that Les Paul was not very fond of the new guitar. At the time of its creation he was under contract with Gibson.  Because of that Les and his wife, Mary Ford, appeared in Gibson advertisements holding the SG.

Paul states the first time he saw the new guitar he was passing a music store window and there was this new instrument with his name on it.

It was not to long after that, Les ended his affiliation with Gibson. Some surmise it was because he was angry about the SG and others contend he was divorcing his wife and did not want her to receive any royalties from guitars being sold using his name. Whatever the case Les Paul asked Gibson to remove his name from the guitar.

In 1963 Gibson renamed the guitar the SG Standard. The new SG's outsold the Les Paul single cutaway. In the first three years it was introduced it sold on average 6,000 units each year, while the LP only sold 1700 units during 1958 through 1960, its final three years.

The body of the SG was thinner than its predecessor and the neck had a very slender profile with no heel. The neck joins the SG’s body at the 22nd fret. This makes playing an ease. However some luthiers claim it is a bit of a problem when the guitar falls down, it generally breaks at the neck or head joint.

1963 SG Standard
The SG Standard came with two nickel plated Gibson PAF Humbuckers, volume and tone controls for each pickup and a three way toggle switch. The first models included a nickel plated Gibson side-to-side Vibrola. It was later offered with a Bigsby vibrato tailpiece or a Gibson Maestro Vibrato, with the long metal medallion that stretched from the end of the vibrato to the tailpiece.

Gibson also offered the beautiful SG Custom. This was the guitar that caught my eye at the music store. This beauty had a clear white finish and three gold plated Gibson PAF Humbuckers.  The Custom came entirely with gold plated hardware. Some early SG Customs came with a short Gibson Vibrola instead of the one with the full cover. There are also some SG Standards and Customs that feature with Gibson’s Maestro Vibrola that have a white plastic handle on the tip of the arm. This option was introduced as a option in 1963. The Kluson knobs had white molded plastic buttons.

The SG Custom's three pickups, were designed to work in the following manner. The two volume control and two tone controls were for the bridge and neck pickups. The middle pickup had no controls and was designed to work with the bridge pickup. On the original models the three way toggle switch controlled the neck pickup and the middle and bridge pickups out-of-phase and the middle and bridge pickups in phase.

When the change was made to Bigsby vibratos on some SG Customs a few came with pearl inlaid ebony at the base of the vibrato. This was offered in 1962.

In 1961 the Gibson SG Standard (Les Paul) sold for $310, which was a substantial price in that era.

The original SG bodies were all made of solid mahogany. The SG Standard came with twin humbucking pickups, a mahogany neck with an ebony fretboard that was inlaid with pearloid trapezoidal makers.

Some came with the Gibson Vibrola side-to-side vibrato unit. Later this was replaced by a Bigsby B5 unit or the Maestro Vibrato. All hardware was nickel plated except the tuners, which had molded plastic tips.

All of the SG Standards and Customs came with Gibson’s Tune-O-Matic bridge, however the SG Junior and SG Special came with Gibson's wrap-around bridge.

No matter the model the SG neck is always a set in neck. As with many Gibson guitars, the SG neck is a 24 ¾ inch scale. The SG Standard and Custom have bound necks and the logo Gibson inlaid in the headstock, while the SG Junior and Special came with white dot position markers and a silk screened Gibson logo on the head.

Just like the Les Paul, Gibson offered some less expensive models. They were the SG Junior and the SG Special. The SG Junior came with one P-90 single coil pickup in the bridge position, while the SG Special came with twin P-90 pickups. The pickups came with a black plastic cover.

In 1962 Gibson realized the problem with the neck and thickened the profile.

By 1964 Gibson decided to use six screw to anchor the pickguard instead of four.

By 1966 Gibson gave its budget Melody Maker guitar the SG shape and offered it with a Pelham Blue or Fire Engine Red finish. Gibson also offered SG’s in the Pelham Blue finish, however they never caught on.

In 1966 Gibson redesigned the SG’s neckset and heel and enlarged the pickguard. Models sold from 1961 through early 1966 came with a small pickguard. The new pickguard was nicknamed the Batwing.

There are a few unusual Gibson SG guitars that were introduced in 1971 and both were discontinued the following year. The first is the Gibson SG Pro. This was a cherry red model with twin P-90 pickups, a Tune-O-Matic bridge and a Bigsby vibrato tailpiece.

The neck was unbound with a rosewood fretboard. The markers were white dots and the logo was silk screened on the headstock. The unusual feature was the triangular shaped black pickguard and the semi-circular black plastic panel that held the controls and input.

The guitars controls consisted of two volume and two tone potentiometers with black witch hat knobs and a three way toggle switch, all housed on the panel.

The other Gibson offerings were the SG 100, SG 200 and SG 250. These were really odd instruments that were offered around late 1970 or 1971. All had the SG style body, but this time it was made out of maple, however there are examples made of mahogany.

The necks were set maple with 22 frets on a rosewood fretboard and dot inlays. The headstock was black with the Gibson logo silk screened in gold ink.

SG 100
The SG 100 came in cherry red or walnut and had one slanted single coil pickup with a black cover similar to what one would find on a Melody Maker. This time it was in the neck position. The pickup cover was surrounded by a nickel plated base. It was offered in cherry or walnut.

The control plate was made of a rectangular piece of nickel plated metal and slanted at the lower bout.

This housed the volume, tone controls and an input. This guitar also came with a nickel plated hand rest adorned with the Gibson logo that fit over the guitars redesign Tune-O-Matic bridge. This bridge was different from Gibson’s normal one. It was more like a Fender hardtail bridge.

The SG 200 was the same as the 100, but came with two similar pickups. The control plate was a little longer to accommodate two on/off slider switches, one per pickup. It came in cherry red and walnut.

The SG 200 was also available with a Maestro Vibrola. Some of the SG 200 came with a trapezoidal pickguard.

SG 250 and SG 200
The only differences between the SG 200 and SG 250 were the finish and the pickguard. The SG 250 came in a cherry sunburst finish. This series of guitars all had nickel plated hardware. The tuners were by Kluson.

Perhaps the reason these guitars were not popular had to do with the design. The neck, fretboard, and strings were parallel to the top of the guitars body. This resulted in the guitar having a high action for all of the SG 100 line up. Plus the SG 100 series single coil pickups all sounded tinny.

As I stated, this line only lasted a year and was replaced in 1972 by the SG I, SG II and SG III.

The SG I appeared to look like the SG Junior. However it came with one mini humbucking pickup in the bridge position that had a black plastic cover. It had a trapezoidal shaped pickguard and a semi-circular black plastic control panel on the lower bout, similar to the SG Pro. This housed the volume, tone controls and the guitars input. Most players at some point, discard the pickguard.

The SG II was similar to the SG I except it came with twin mini-humbuckers. The control panel was similar as well but for the two slider switches to control the pickups off and on function.

Once again the SG III was the same guitar as the SG II, except once again it had a cherry sunburst finish. All guitars in this series were made of mahogany. Gibson used Kluson tuners and a wrap-around bridge.

You will find a lot of examples of this guitar with the bridge changed out to one that is adjustable. The SG I and II came with cherry or walnut finishes.

In 2007 Gibson issued a new SG III guitar, but this one was quite different from the original. This guitar had a white pickguard that covered most of the bodies’ upper section. Housed in the pickguard were three single coil pickups. The single volume and tone control was on the guitars lower bout. Additionally a 6 was rotary knob was placed near the other controls. This control allowed the player to select all pickup combinations.

The hardware was nickel plated. Tuners were by Kluson. The tail piece was a stop unit with a Tune-O-Matic bridge.

Steve Moore's SG
There are innumerable SG models that Gibson came out with over the years. One model that I have not been able to track down had an elaborate design of grapes, leaves and grape vines carved in the upper and lower bout. A good friend mine owned one of these.

It had two chromed humbucking pickups and nickel plated hardware including the Tune-O-Matic bridge and stop tailpiece.

I know Guild made a guitar with carving that looked like an SG.

Guitarist Steve Moore also owned and played one, but his was heavily customized with an extra pickup, additional controls and a gold plated Gibson Vibrola

Perhaps the most unusual SG was Gibson’s Robot Guitar. This SG comes with an auto tuning system developed by the German company Trionical.

The Tune-O-Matic bridge houses individual piezo units that are connected to a micro processor. The computer then analyses the signal and commands each of the guitar's Powerhead Locking Tuners which automatically pull the strings into tune. These tuners operate by means of small servo motors.

The Robot guitar contains a small lithium rechargeable battery to power the motors. Gibson offers this technology to several of its models.

One guitar that is mistaken for an SG is the redesigned Melody Maker. This guitar was first produced in 1969 as a replacement for the double cutaway Melody Maker. The newer version was given the SG shaped body with one, two or three pickups.

There were differences between the Melody Maker and the SG starting with the Melody Makers narrow headstock, single coil pickups with white plastic covers, cheaper tuning pegs with plastic white buttons and a large white pickguard.

The one pickup model had a single coil pickup in the bridge position. The next Melody Maker added a neck pickup and two on/off slider switches, plus a volume and tone knob for each pickup. While the rare three pickup model came with, you guessed it, three single coil pickups.

However there was only one three position slider switch. The instrument came with two volume and two tone controls.

All of the three pickup models I have seen came with a Gibson Maestro short arm vibrato with the plastic tip on top of the arm.

The biggest complaint about this era’s Melody Maker with the cast saddle bridge and the cheap tuners. This along with the vibrato made tuning difficult. I am told the pickups are great and sound warmer than Fender pickups.

The original models came in Fire Engine Red or Pelham Blue. A burgundy version was added a year later as was Inverness Green.

Some old Pelham Blue models are mistaken for green. This also happens with old Pelham Blue Fenders as the yellowing effect of the clear coat lacquer seems to fade to a greenish hue through the years.

Famous celebrities have, from time to time, made the Gibson SG their signature guitar. Angus Young would never be caught performing with anything else.  George Harrison, Eric Clapton, Tommy Iommi and Todd Rundgren have all been associated with the Gibson SG Standard.

The one standout SG was owned by Eric Clapton during the Cream years. It started out as a cherry SG standard with a Gibson side-to-side vibrola. The year 1967 were the days when Psychedelic art was in fashion.  Clapton had his SG repainted by Dutch artists Marijke Koger and Simon Postuma who were part of a pop artists group called The Fool Collective.

Actually it was the Cream’s manager, Robert Stigwood, who contacted Koger to do artwork for the band.

Clapton’s SG was repainted with Psychedelic designs, as was Ginger Baker’s drum set. A Fender Bass VI was painted in Psychedelic patterns for Jack Bruce, but he preferred his four string bass.

Clapton referred to this guitar as The Fool, after the artists.

The Fool - 1964 Gibson SG

The history of The Fool becomes a little murky after Clapton retired the guitar. He either gave it to George Harrison or Jackie Lomax. There are some who believe Jackie Lomax acquired it from Harrison. Lomax then sold the guitar to Todd Rundgren for $500. Rundgren renamed the guitar, Sunny. In 2000 Rundgren put Sunny up for auction and it sold for $150,000. This guitar has been copied numerous times.

1960’s Silvertone Amplifiers

For my best friend Doug Abbott. 1951 to 1999
♫ ♪ Lay down your weary tune, lay down. Lay down the song you strum. And rest yourself 'neath the strength of strings. No voice can hope to hum ♫

I was 11 years old when I first heard the Beatles. By the time I was 12 there was no question about it, I had to have a guitar. I was fortunate. Dad bought me a very used Stratocaster for $150 USD. I saved up $200 to by a Fender Deluxe Reverb amplifier.

But some of my friends couldn’t afford Fender, so Silvertone amplifiers were the next choice. Looking back, there were some other fine amplifiers that were probably in the same price that came with finer construction, but a Silvertone amplifier was so accessible. The inner working may have been slightly different, but they were well made.

In the 1960’s we had no internet, no amazon.com, no Musicians Friend. Heck we had dials on our telephones instead of buttons.Twice a year we would get a big Sears catalogue in the mail. Some lucky folks got both Sears and Montgomery Wards catalogs.

My friends and I would head right to the guitar advertisements that promised, “a professional sounding instrument made of the finest birch.” The electric guitars were generally made by Harmony, Valco or Kay.

Sears amplifiers originally were made by Valco, but by the 1960’s Danelectro was contracted to build amplifiers and put the Silvertone emblem on the grill cloth.

Of course we all wanted the biggest and loudest amplifier we could afford.

Silvertone came through, although there were some quality issues.

The electronics were fine. The reverb sounded a little tinny, considering it was housed in the amplifier. Other than that it was a great amp, especially for the money.

The problem was the cabinets. Silvertone/Danelectro used particle board to construct its cabinets while Fender used white pine. The other issue was the speaker baffles were constructed of ¼” masonite boards.

You can see through the grill cloth some of the routing used for the speakers was not even round; it was just cut in a square placed in a diamond pattern.

The covering used on most Silvertone amplifiers was merely inexpensive gray and black fabric that easily was damaged if the amplifier was knocked against a corner.

Frequent bumps and knocks damaged the particle board. These amplifiers were purposely made on the cheap to be affordable to everyone.

However the electronics in the Twin Twelve amplifiers did not seem to be adversely affected by the cheap cabinet design.

The story was different for the tube bass amps. The speaker rattled like crazy. Tightening the nuts and screws on the basket did help a little. Possibly the best fix was to remove the particle board and replace it with solid wood.

As the years went on to the later 1960’s bands tended to become louder. The Twin Twelve models were around 50 watts, similar to a Super Reverb and generally had no trouble being heard; however the Sears bass amps were only around 23 watts, which were not loud enough. In those days, no one thought of miking the amp through the PA system. This is the model 1473 with a 15" speaker.

Today what amazes me is the amount of money these old amps are commanding.

Possibly the best and the most desirable Silvertone amplifier is what we referred to as the Silvertone Twin Twelve or model 1484. This amplifier came with a speaker cabinet that was slightly smaller than a 1963 Fender Bassman or Bandmaster.

The closed back cabinet enclosed two 12” 8 ohm Jensen speakers wired in series. In the bottom of the cabinet there was a space to store the separate amplifier unit for travel.

The 1484 amplifier came with a non-removable 25 foot cord that attached it to the speaker cabinet. The amp produced 50 watts of tube power, which theoretically should have been at least as loud a Fender Super Reverb. However it was not due its design.

This 50 watt amp came with two separate channels, each with two inputs. Each channel came with knobs for volume, bass and treble. As true with Fenders of that era, one channel had no effects and the other was connected to the reverb and tremolo.

The tube complement consisted of 2 - 6L6GC power tubes, 2 - 6CQ7 – one was the phase inverter and the other was the reverb driver – 3 - 12AX7 preamp tubes and another 12AX7 for the tremolo circuit. The rectifier was solid state.

Because of the voltages on the power tubes, Fender amps were much cleaner than Sears amps, however these Silvertone models deliver a nice compressed sound.

The Bass and Treble controls are interactive with the volume. The higher you turn up the bass and treble produces more gain this amplifier produces.

One trick, most owners of the 1484 figured out was to turn the amp’s volume all the way down and then turn the reverb potentiometer all the way up. This produces some other-worldly stuck in a cave sounds.

In 1963 and 1964 you could buy a 1484 Twin Twelve for $149 USD.

As guitarists yearned for louder amplifiers, Sears produced the 1485 amplifier. The circuitry was similar to the 1484, except this amp had 4 6L6GC tubes and produced 100 watts of power. And instead of twin 12 inch Jensen Special Design speakers, this amp came with six 10 inch Jensen Special Design speakers.

The Silvertone 1485 amp came with a complement of ten tubes. I saw two websites stating it had 5 rectifier tubes, which I find hard to believe.

From looking at a schematic I know the amp had 4 6L6GC power tubes team up in pairs and 2 6CQ7’s.

One was the phase inverter and the other was the reverb driver. That left 4 12AX7 tubes, 3 of which were preamp tubes and the 4th took care of the tremolo circuit.

In 1965 the Silvertone 1485 amplifier could be yours for $239.95 USD.

My best friend played bass. He saved up his school lunch money and sent off for a Sears 1483 and a matching 1444 Dano made single cutaway-single pickup bass. This was the bass guitar with the dolphin nose headstock.

The Sears 1483 was a 23 watt amplifier that came with a 15 inch Jensen Special Design Speaker. I do not know why the wattage was only half of what the guitar amps produced.

My thought is Sears/Danelectro wanted to keep the sound down to prevent speaker rattle, which is just what happened to my friends amplifer.

The 1483 Silvertone Bass Amp was a two channel amplifier with two inputs for each channel. The channels were identical and there were no effects. The tube complement included two 12AX7 preamp tubes – one 6FQ7 phase modulator – one 5Y3 rectifier tube and 2 6L6GC power tubes.

The controls were volume, treble, bass for each channel. The switches on the front were standby / operate, the all important ground switch and an on/off switch.

In 1963, wall outlets accepted only electric cables with two prongs of equal size. A guy could get a shock if he touched a microphone connected to a P.A. with reverse polarity. The biggest issue was 60 cycle hum through the amplifier. The ground switch prevented both situations. Despite being called a ground switch, it really did not 'ground' the amplifier.

The model 1483's 15 inch Jensen speaker that was housed in the cabinet and had a huge magnet. The cabinet design was different from the 1484.

The speaker was mounted on the left side of the cabinet and the storage area for the amplifier was on the right side and the amp head was stored vertically.

In 1963 and 1964 this was a bargain at only $99 USD for the amplifier and $79 for the guitar. My dear friend Doug went crazy due to the rattling speaker, so he replaced it with a Utah speaker. Then saved up and bought a JBL Lansing speaker. He then stuffed the back full of fiberglass insulation. He finally saved up enough for a Fender Bassman.

In my opinion the 1483 would have made an excellent guitar amp as it produced as much power as a Fender Deluxe, only the Sears amp used 6L6 tubes instead of 6V6’s.

The predecessor to the 1484 was a combo amp designated as the Silvertone 1474. This amplifiers circuitry was similar to the 1484, however it was a combo amp and was made by Danelectro.

In fact it was similar to an amplifier Danelectro sold under it's own brand called The Twin Twelve.

The amp included twin Jensen special design speakers, two channels; one clean and one with effects. Each channel had a volume, treble and bass control. The 1474 came with a Hammond reverb unit and tremolo. It produced 50 watts from 2 6L6GC power tubes.

While the model 1484 came with grey and black fabric covering, the model was 1474’s covering was solid black with white piping around the front of the cabinet.

It sold for $139.95 in 1961 and only was offered for one year.

As for the smaller amplifiers that Sears and Roebuck offered, the first was the Silvertone 1471 was built by Danelectro to compete with Fender’s new Champ model.

This amp produced 5 watts of power into an eight inch Jensen speaker.

It came with a volume and a tone control. This model sold from 1961 to 1962.

The Silvertone 1472 was the next model offered and was sold from 1961 to 1963. This amp put out 10 watts into a 12 inch Jensen special design speaker. This dual channel amplifier controls were volume, tone, volume, tone and it came with tremolo controls labeled speed and depth. It sold from 1961 to 1962.

The Silvertone 1482 was similar to the 1472, except it offered 15 watts of power. The key difference was the extra 5 watts and the handle on the top was flexible, while the handle on the 1472 was solid and known as a ‘refrigerator handle.’

The 1482 was offered in 1963 through 1968. It too came with a Jensen 12 inch special design speaker. Both amps sold for around $69 USD. 

Model 1448

The final Silvertone amplifiers that were very popular in the 1960 decade were the amp-in-a-case models.

Silvertone offered two models in the 1960’s;  four if you considered the value of the guitar that came with it.

From 1962 to 1965 Silvertone offered models 1448 and 1457. Both were made by Danelectro.

The wooden guitar cases came with a section of gray grill cloth which hid a tiny 3 watt tube amplifier with a five inch speaker. The speaker frame was designed to prevent damage to the speaker.

The model 1448 amp had a rectifier tube, a preamp tube and a 6V6 power tube. There was one volume control. The player would remove the guitar and stand the amp on its bottom side with the case opened to hold it upright.

There were some differences in the 1448 and 1457 models. The 1448 came with a single pickup Danelectro masonite guitar and only a volume control on the amp.

The 1457 model contained a twin pickup Dano guitar, a volume and tone control, tremolo knobs, cord, footswitch and a 45 rpm ‘how to play the guitar’ record.

The 1448 sold for $68 USD while the 1457 sold for $100 USD.

Prior to the introduction of the 1457, the model was designated the 1449. The 1449 was first made available in 1963 and replaced by the 1457, which was essentially the same amplifier and guitar.

The 1448 sold from 1962 to 1965 and the 1457 sold from 1964 to 1966 when both were replaced by the model 1451.

The Silvertone model 1451 came with a giant six inch speaker attached to a three tube (rectifier, power and preamp) and a single volume control. The guitar was made of wood instead of masonite on a pine frame. The neck and headstock were still the same. This baby pushed 5 watts of power.


The Silvertone/Danelectro model 1452 came with an 8 inch speaker, 5 watts of power, 4 tubes and a Danelectro solid wood guitar with two lipstick pickups and a tremolo bar. The 4 amp controls supported volume, tone and speed and depth for the tremolo.

One amp-in-case/guitar combo worth mentioning is actually from the 1940’s. This unit was made by Valco and designated the Silvertone 2323.

 The amplifier unit was housed in the guitar’s case. It produced 3.5 to 4 watts of power through a rectifier, power and preamp tube. The speaker was 6 and a half inches. The only control was volume with a chicken head knob.

The guitar was a lap steel also made by National/Valco. It was made of wood with a mother-of-pearl covering. It came with a single pickup and a single volume control and a Roy Smeck Guitar instruction book. These instruments are extremely scarce.
