Guitar-related Circuits
This directory contains various guitar effects schematics. There are
so many of them, I decided to create for them a directory all of their
own.
Files in this directory:
Most of the files found in this directory were contributed by

4 band equalizer circuit
-
angrybd3.gif
angrybd3.ps.Z
-
(Angry Beard 3)
I won't claim this is the best fuzz out there. Its a very simple
circuit and sounds pretty grungy but it gets the job done. Uses a
overdriven germanium transistor.
- axgrindr.ps.Z
-
axgrindr (Axe Grinder Distortion)
Nice sounding distortion pedal with blend controls and surprising
versatility.

has two controls for treble and bass brightening. The other just boosts
upper frequencies.

Looks like one of the earlier models from the components but I could
be wrong. Still its hard to be the Cry Baby sound for what it is.

device to achieve its enveloping effects.

If you don't know what this is, then don't ask. Consider yourself
lucky to be blind to the hype.
