Tools, Tones and Toys for Guitarists
From what I can see, the only difference between the two schematics below is the 200ohm resistor after the rectifier (shown on the V-1-3 schem). There are some variations of cap values that can be ignored, such as 4n7 vs 5n etc. I think this may be similar to the AC15 schematics, where Thomas Orgain … Read more

Another simple one knob tone control, this time from the Marshall 18w amplifier, or the model 1974x, whatever you prefer… Marshall used two different tone controls in the amp. A lot of folks build the 18w lite, which is just the normal channel of the amp, and they often use the trem channel tone … Read more
This is the classic single-knob tone circuit made famous by a number of Fender amps—most notably the 5E3 Tweed Deluxe. Despite not inventing it, Leo must have thought that he nailed it when he first dropped this into a guitar amplifier: it’s simple, clever, and very musical. Despite using only a handful of parts, it … Read more
