With apologies to Ralph Campbell for lifting the copy but this is a great description and I’m sure the effect is killer:
“Fuzz Face Experimenter (NPN) is a Fuzz
Face with sockets for Q1, Q2, input cap, and output cap on the top of
the enclosure. All four components can be changed quickly and easily
with the included transisitors and caps. The included cap values are
0.01uF, 0.1uF, 1uF, 2.2uF, and 3.3uF. Included transistors are 2N2222,
2N3904, 2N5088, and 2N7000.”
“With the included components you can create
everything from “I can’t notice fuzz” to “Blow the hair off you genitals
fuzz”. This box is hours of fun, with nearly limitless options to try.
The controls include volume, fuzz, and bias. Runs on 9v battery or
pedal board power. The on/off switch is 3PDT for true bypass.”
Check him out on eBay.
