Les discovered the solution to this was lo-impedance input. Gibson added this feature to their Les Paul Recording model. The guitar came with two slanted low impedance pickups with Gibson logo molded on covers.
In other words, with the transformer off for recording in a studio plugged directly into the board, the low-impedance mode gave much cleaner tracks and broader frequency bandwidth that could be tweaked in the mix.
The guitars two Low Impedance humbucking pickups that were stacked and angled.
This guitar was designed to sound best when plugged into a mixing desk at (Low Impedance setting). When used with a regular amp, you had to engage the inbuilt impedance transformer. Controls were relatively complex — Volume, Treble, Bass, “Decade,” Microphone Volume, Pickup Selector, Tone Switch and Phase Switch on its large inlay panel. The Decade switch was designed to “tune”/alter treble harmonics, for "biting" or "silky" highs. And the Decade switch was feasibly the start of a guitar culture joke: although called the Decade, the selector switch had one more position. It actually went up to 11
