Haven't seen this one around, also, there's not much information on the web. A friend got one used in really good shape, despite being such an old unit.
Anyway, my friend let me take a look inside, I traced it and made a layout, nobody has verified none of them, but I'm pretty sure both are allright.
I guess it's a silicon based fuzz, because I don't know the transistors and don't know the clipping diodes neither. The tone control is really weird.
It's a nice sounding effect, It might be a little brittle and thin on some amps; A strat plugged into it and then into a Blues Jr. amp sounded pretty good to me, nice subtle fuzz, gives a nice crunch when playing rythm.
Regarding the layout Transfer, I couldn't scale it properly, if I reduced its size, then the image would distort, so, sorry for that inconvenience.
Hope you like it.

Well, at least my schem has colors on it.![]()
But, honestly, this seemed such a unique creature I thought it hadn't even been copied.
Morecowbell, I got my hands on an old (really old) Electro harmonix Fuzz-wah, and I also haven't found anything on it, is it worth tracing?, I don't know, maybe you or someone else around here already has it or a similar one. Thanks in advance.
Fuzzer wrote:Yes man, thank you very much, is pretty much the same, the wah part is identical.
There are some differences in the fuzz circuit though, according to my drawing, (I'll post the gutshots later anyway, it's always nice to see effects innards), the input cap is .047u, and in the second feedback loop, the clipping diodes are shunted with a 470k resistor and a 0.1[nF] cap, maybe to tame the highs a little, I guess. Also, some of the 680k resistors are 1M in the one I had.
By the way, have you heard it in action?, the wah sounds great to me, really raw and angry, I like that, and the reverse mode is pretty interesting. It's a uncomfortable pedal though, you'll see when I post the pics in other thread.
Thanks again.
