Class D Guitar Amplifiers May Be The Future

 

The First Commercially
Available Class D Amp 1964
Perhaps you were not paying attention, but Class D guitar and bass amplifiers are currently becoming very popular lately. Due to the lower costs many companies are pushing these class D modeling amplifiers over the original versions. Some players seem to like the to.

Fender Tone Master
Deluxe Reverb

Fender started with the Fender Mustang modelling amplifiers and currently are championing their Fender Tone Master series, which include the Tone Master Deluxe Reverb, The Tone Master Twin Reverb, The Tone Master Princeton Reverb, The Tone Master ’59 Bassman and others. 

Fender Tone Master
Twin Reverb

All of these amplifiers feature much more power than the originals and weigh so much less. The 100 watt  Twin Reverb that I used to tote around In the 1970’s weighed over 80 pounds. The Tone Master version comes In at a mere 33 pounds and  produces 200 watts of power into its twin 12-inch speakers.

The reason for most of the weight in the older versions was due to the necessary large transformers. 

Class D Amplifier
Due to the design of Class D amplification, the huge power transformers are no longer necessary, Class D amplifier utilize  a switching power supply (SMPS - Switch Mode Power Supply) instead of a large traditional power transformer. 

The SMPS is much more efficient than the traditional AC stepdown transformer to convert AC power to Direct Current and can be made much smaller and lighter.

Where traditional Class A or Class AB tube amplifiers were the standard for years, the Class D amplifiers operate more efficiently. With the advantage of modeling software and hardware the guitar and bass sounds available are very close to the original tube versions. 





There are a lot of companies that have offered class D amps that you may not have known about. In the early 2000's Crate offered the tiny Power Block amplifier head that produced 150 watts of class D power.


 It was small enough to fit in a guitar case. 

Acoustic Image Clarus

Acoustic Image amplifiers were popular with Jazz players due to their compact size and incredible power derived from the class D design. 


Ampeg V12 Bass Head
Some Line 6 amps utilize class D.  And there are so many bass amplifiers that utilize class D. TC Electronics, Gallien Krueger, some Ampeg, and even some Mesa Boogie all have class D power. 

Though this all seems to be a perfect solution, class D amplifiers may have some drawbacks. including potential for distortion, complexity in design, and sensitivity to power supply noise. And though they are  generally more efficient, class D amps still require protection against overheating, especially when delivering high power for extended periods,  

Tone Master Super Reverb
'65 Tube Super Reverb

There is criticism about Fender's Tone Master amplifiers by those comparing them to the original tube models these amps are based on. In my opinion the difference is minimal. The Fender Mustang series has been around for years and most users are quite satisfied with that product.
 
Some of the early Class D amplifier designs had a reputation for failure, however modern, high-performance designs are becoming more reliable.

Happy 90th Birthday Carol Kaye - Bass Player On 10,000 Recordings

 

Carol Kaye
Carol Kaye is THE most heard bass player ever recorded. Her bass and guitar can be heard on  over 10,000 recordings and film soundtracks and television themes. She describes herself as a 'session player' to distance herself from The Wrecking Crew name. 

Carol Kaye 1935
Carol started out playing in clubs with jazz bands until Sam Cooke's producer once asked her to fill in on a recording session. The money she earned from this made her realize that she could earn doing recording sessions than she earned on club dates.


Soon this slender, young, blond girl fit in with session musician that were made up mostly of male players. Carol states she was a third or fourth call as a guitar player until that session in 1964 when the bass player failed to show up for the gig. There was a Fender Precision bass in the studio, and she volunteered to play it on the session. Soon afterwards she became the first call bass player  due to her guitar skills and sight reading ability. Now at 90 years old she describes her memories as a session player in a way that you would think you are listening to someone that is considerably younger. 

1960's Artists


Currently many recordings feature synthesizers, auto-tune, and digital effects recorded on computers. But historically music was produced in a large studio with an orchestra full of professional musicians usually backing up the vocalist(s). Music was recorded on analog tape with just a few tracks. For those of us who grew up listening to the music of the 1960’s and ‘70’s this is what we were used to hearing.




The recorded music of the past featured a group of professional session musicians that often were the same group of players on nearly every well known song. To those musicians it was a job. They got paid,  They went home. But for the most part did not get credit.

This was the case in most large cities where recording took place in New York City, Detroit, Nashville, Memphis, and even Cincinnati, Ohio., During the rock era much of the hit recordings were done in several Los Angeles studios by a group of talented musicians nicknamed “The Wrecking Crew” by drummer Hal Blaine.

Carol Kaye
At that time many of those popular songs featured Carol Kaye, who played the bass guitar on almost 10,000 of those recordings.  So many of these songs became hit records. 

Carol Kaye is indeed a legend and an American treasure. You may have never heard her name but I guarantee that you have heard her distinct bass guitar lines. Ms. Kay  recently celebrated her 90th birthday.

Other TV themes that feature her bass guitar lines include Cannon, The Streets of San Francisco, Mission: Impossible, M*A*S*H, Kojak, Get Smart, Hogan's Heroes, The Love Boat, McCloud, Mannix, It Takes a Thief, Peyton Place and the previously mentioned Cosby Show. She is credited with performing on the soundtracks of Hawaii Five-O, The Addams Family and The Brady Bunch along with Ironside, Room 222, Bonanza, Wonder Woman, Alias Smith & Jones, Run for Your Life and Barnaby Jones. 

Carol Kaye played 12-string guitar on several Sonny and Cher hits, as well as on Frank Zappa's album Freak Out! 

Her favorite producer was Quincy Jones, and favorite drummer was Earl Palmer.

Carol Smith nee Kaye was born on March 24, 1935. Her career as a musician has spanned 50 years. 

Carol Kaye Through The Years 
She began playing guitar in her early teens and after some time as a guitar teacher, began to perform regularly on the Los Angeles jazz and big band circuit. She started session work in 1957, and through a connection at Gold Star Studios. 

She began working as a guitar player for producers Phil Spector and Brian Wilson. As previously mentioned she was the first call bass guitarist on so many session. She also authored a series of tutoring books such as How To Play The Electric Bass, which she still sells through her web page. Carol became less active towards the end of the 1970s, but has continued her career until retiring in her 70's by doing motion picture work.

How To Play The
 Electric Bass by Carol Kaye
She also taught guitar and bass and gave lessons to thousands of students, including notable players John Clayton, Mike Porcaro, Alf Clausen, David Hughes, Tony Sales, Karl E. H. Seigfried, Roy Vogt and David Hungate. 

During an interview she was asked if she was ever upset by being a ‘no-name’ background player, and not enjoying the fame acquired by the big name bands and singers that she backed up. Her reply was no. She got to be home, and enjoy her family, raise her children, and not have to travel. 


Carol (Smith Kaye)was born in Everett, Washington, to professional musicians Clyde and Dot Smith. Her father was a jazz trombonist who played in big bands. In 1942, he sold a piano in order to finance a move to Wilmington, California. Her parents moved, but divorced soon afterwards. When she was young music was the one thing the that united their family. At 13 Carol received a steel string guitar as a gift from her mother and she quickly took to the instrument. So much so that she began teaching professionally the following year. She was born into a Depression Era family and that fueled her strong work ethic.

In the 1950’s Kaye played bebop jazz guitar with several groups on the Los Angeles club circuit, including Bob Neal's group, Jack Sheldon backing Lenny Bruce, Teddy Edwards and Billy Higgins. 


She played with the Henry Busse Orchestra in the mid-1950s, and toured the US with them. 

It was in 1957 that record producer Robert "Bumps" Blackwell heard her play and invited her to do a recording session for Sam Cooke's arrangement of "Summertime" on which she played guitar. This was a wake up call. She realized that she could make significantly more money with session work than playing in jazz clubs, so she decided session work was going to be her full-time career.

 Carol Kaye and The Teen Aires
 
Then in 1958, she played acoustic rhythm guitar on Ritchie Valens' "La Bamba", which was recorded at Gold Star Studios, Hollywood. Through Gold Star, she began to work with producer Phil Spector, playing electric guitar on Bob B. Soxx & the Blue Jeans' "Zip-a-Dee-Doo-Dah" and The Crystals' "Then He Kissed Me", and acoustic guitar on The Righteous Brothers' "You've Lost That Lovin' Feelin'". 


Along with several other musicians including drummer Hal Blaine and guitarist Glen Campbell, her work with Spector attracted the attention of other record producers and she found herself in demand.

She quickly discovered that she preferred playing bass, and found it was a key component of a backing track and allowed her to play more inventively than the relatively simpler guitar parts she had been playing until then. From a pragmatic viewpoint, it was easier to carry a single bass guitar to sessions instead of carrying and swapping between the three or four guitars that session players had to carry with them depending on the song.  

After Wrecking Crew bassist Ray Pohlman left studio work to become a musical director, Carol Kay became the most in-demand session bassist in Los Angeles. However she is remembered by players at those sessions being generally good humored and united by the music. 

Kaye At A Brian Wilson
Recording Session For Smile
Through her work with Phil Spector Carol Kaye caught the attention of The Beach Boys' Brian Wilson, who used her on several sessions, including the albums Beach Boys Today, Summer Days (and Summer Nights!!), Pet Sounds and Smile. Working with him was unlike other sessions, since she was free to work out her own bass lines, Wilson always came in with a very specific idea of what she should play. By Pet Sounds, Wilson was asking musicians such as Kay to play far more takes than typical sessions, often running over ten passes of a song, with sessions stretching well into the night. 

Kaye is often credited for creating the bass line on the Beach Boys' "Good Vibrations" single, although it is not her bass heard on the recording.

Brian Wilson remembers Kay as one of the session players hired for the many sessions devoted to the song: "The bass part was important to the overall sound. I wanted Carol Kaye to play not so much a Motown thing, but a Beach Boys-Phil Spector riff". 


By 1969 Kaye said she was exhausted and had become disillusioned from doing session work, saying that the music had "started to sound like cardboard". At the same time, many newer rock bands disapproved of using session players, preferring to play the instruments themselves. 


In the early 1970s, she toured with Joe Pass and Hampton Hawes, but continued to do some sessions. In 1973, she played on Barbra Streisand's single "The Way We Were", which was cut live.  

In 1976, she was involved in a car accident, and semi-retired from music. In 1994, Kaye underwent corrective surgery to fix injuries stemming from the accident, and resumed playing and recording.  

The Marvelous Mrs. Maisel and Carol Kaye
Carol Kaye is a little miffed that a popular TV series, The Marvelous Mrs. Maisel's character, 'Carol Keen'  seems to have captured her image. In an interview last year she said, "I am not a cartoon!"

She collaborated with Fender to produce a lighter version of the Precision Bass that reduced strain on her back and made it more comfortable to play. In 1997, she collaborated with Brian Wilson again, playing on his daughters' album, The Wilsons, while in 2006, Frank Black asked her to play on his album Fast Man Raider Man. 

Carol Kaye's Equipment
Through most of her early career Kaye's main instrument was the Fender Precision Bass, though she also used the four and six Danelectro basses on occasion. 

By the 1970s, she sometimes used the Gibson Ripper Bass.


It was lighter, and featured twin humbucking pickups as well as a 3 band active preamp/EQ.  


Kaye with Ibanez
Bass and Guitar
She uses Thomastik-Infeld JF344 flatwound strings with a high action and preferred to use guitar amplifiers in the studio when playing bass, including a Fender Super Reverb (to get more treble), an older Fender Bassman with 4 ten inch speakers, a brown Fender Deluxe amp, and a Versatone Pan-O-Flex amplifier. 

Kaye primarily uses a pick, or plectrum, on both guitar and bass, rather than plucking the strings with her fingers. During her peak recording years Carol put a piece of felt between the strings behind the bridge on her Precision bass to enhance the sound and reduce unwanted overtones and undertones.  

If you view the videos below you will note that she puts masking tape on her Ibanez bass for this same purpose.

Kaye with 1946
Epiphone Emperor

She also played an Ibanez RG321 guitar as well as an Ibanez RT150. Very Early in her career Carol Kaye used as series of Jazz style guitars including a 1946 Epiphone Emperor, a 1955 Gibson ES-175, and many other instruments.

Fender Tube Amps For Less Than $400?

 

A Fender tube amp for less than $400? No way! If you don’t mind used equipment, they are available in the used market.  

Pawn Shop Prizes

Back in 2012 Fender introduced their Pawn Shop Prize amplifier line up. These included four tube-based amplifiers that were offered that year. None of which resembled a Fender product, and none even have the Fender logo. 

The idea that the designers had in mind were amplifiers, perhaps from Montgomery Ward or Valco that you may find in a pawn shop. 

Bruce Zinky
All of these amps were designed by Bruce Zinky. He worked for Fender for a number of years and was responsible for some of Fenders classic amplifiers including the Pro Junior, the Prosonic, the Tonemaster, the Vibro King and the Vibrolux Reverb. 


When he left Fender Zinky set up his own company and produced amplifiers under his own name. You may remember Smokey Amps. These were tiny 1 watt solid state amps that were originally placed in a cigarette package. However I am digressing. 




Fender Pawn Shop Prize Amp
At the time Zinky was tasked by Fender to come up with the Pawn Shop Prize amplifiers. These went along with their Pawn Shop Prize guitar line up. The amps and guitars were featured at NAMM in 2012.  


I would say the most popular amp in the series was the Excelsior. This amplifier pumped 13 watts of class AB power into a 15-inch Fender special design speaker. The control panel was very minimal. A volume and a tremolo knob, plus a Bright/Dark switch. 


Like many amplifiers from the 1950’s and 60’s it had three input switches labeled Guitar, Mic, and Accordion. 

The tube configuration included a pair of 6V6 power tubes and two 12AX7 preamp tubes, one controlled the tremolo circuit. On the used market The Excelsior is selling for an average of $375 USD. The 2012 version came only with a brown covering. The 2013 version was offered with colored covering and sold for around $100 more. 


The Excelsior amplifier brings to mind the 1960’s Supro Thunderbolt amplifier I used in 1965. The Supro had a 15-inch speaker, and had more power, rated at 35 watts based on its twin 6L6 power tubes, a 5U4 rectifier, and a pair of 12AX7 preamp tubes. 



The Thunderbolt was marketed as a bass amp, however it was inadequate due to the baffle buzzing. However it was a wonderful guitar amplifier. Controls were very basic as it only had a volume and tone control. 

The Pawn Shop Prize Excelsior gives out a clean sound with the volume going up to one third volume,  after that it breaks up considerably. If you are looking for a Blues amp, you may want to consider the Excelsior.  

Fender Vaporizer

The Fender Pawn Shop Vaporizer was an interesting amp. This amp had a pair of 10-inch Fender Special Design speakers and it pumped 12 watts of AB power from its twin EL84 power tubes. The preamp section was solid state. 

Vaporizer Controls
The control panel included volume, tone, and reverb knobs, and inputs for normal and bright. One trick this amp accomplished with its reverb knob allowed the player to turn off the volume and turn up the reverb. This produced an ethereal sound. (You could do the same on a Silvertone Twin Twelve)


Vaporizer (back)
The bonus feature on the Vaporizer was the footswitch that was included. Depressing this bypassed the volume and tone circuit producing a raw gritty overdriven tube amp sound. 



Colors for The Vaporizer
This amp was offered with red, blue, and surf green coverings. I am seeing these amps selling on the used market for around $400. 


As I recall Music Man amps and some Peavy amps were designed with a tube power amp and a solid-state preamps. This caused those amplifiers to have a little more headroom. 






The next Pawn Shop Prize amplifier is the Fender Ramparte. (That is the way Fender spelled it) 






Ramparte Controls

This was a class A amplifier utilizing a single 6L6 power tube and a pair of 12AX7 preamp tubes producing 9 watts of power. This amp had a Fender special design 12-inch speaker. 

The Ramparte was a two channel amp that had a "Cool" section and a "Hot" section with chicken head knobs. Minimal controls were a just a volume knob for each channel and inputs for each channel. 

The Cool section was voiced to produce a clean tone that went from warm and clean to mildly gritty, while the Hot section delivered killer overdrive tones. There were no tone or EQ controls. 

On the used market these amps are selling for  $300 to $380 USD.



The Greta by Fender
The last Pawn Shop Prize amplifier is the Greta. This tiny amp looks more like a retro Japanese radio than a guitar amplifier. It produces a mere 2 watts of class A power driven by a single 12AT7 tube for the power section and a single 12AX7 preamp tube into a tiny 4-inch speaker. 

The Greta amplifier was designed as a practice amp, but can be mic'd for recording purposes. It has one channel with a volume and tone control on the amps front with an old school VU meter. 

The Greta (back)

On the back side there is a guitar input, a 1/8" auxiliary input, a line out and  an external speaker output plus the on/off switch.  Despite its size some player like this little amplifier.  


I am seeing The Greta being offered for $220 to slightly over $330 on the used market.  If you are looking for an inexpensive and unique tube amplifier the Fender Pawn Shop series might just be for you.   

To be fair, I looked on Reverb to see if there are any used tube amplifiers that are available for under $400. 




There are currently six Fender Blues Junior amps priced below $400 and three selling for $400. 






There are also three Pro Junior amplifiers selling for less than $400. 




There are also several Fender Vibro Champ XD amps for sale for $325 and below. 





Another option is the Fender Super Champ XD which can be purchased for around $250 USD. 






The Fender Pawn Shop Prize series of amplifiers were truly unique creations from a time when the Fender Musical Instrument Company was willing to think outside of the box. 

While the Blues Junior and Pro Junior were manufactured in Mexico, all of the aforementioned amplifiers are of Chinese origin.
