Hi friends!
This is the third (and possibly final) Shin-Ei FY-2 Companion fuzz I've built. This is also my first completed build since I started posting here.
Mark Hammer is a champion of this circuit and has some great mods for it.
I added his 3 way tone control, a mids control and a bass control (which is subtle)
The first time I built one of these I used Mark Hammer's "Bottom" switch to control bass. On this build I replaced the 100k resistor in parallel with the 0.047 cap with a 100k pot. Both are subtle, but I decided I'd rather have it than not. This idea came from Luciferstrip from a thread on diystompboxes.
So happy I found this thread just as I'm about to build my first pedal - an FY2!
Quick questions, should I understand that for the "bass control" you changed the 100k resistor for a 100k pot and ditched the on/off switch that took the 0.047 out of the circuit? I don't see the switch on the pedal (as I assume the only one I see is the on/off/on of the 3-way tone control), so I'm guessing this is the case. If it makes no sense to do both (100k pot and switch to disconnect the cap) I might just do the switch . . .
Lastly . . . the transistors . . . I'm not looking for one single definitive answer here, but maybe a few different things to try. Modern vs NOS? Silicon vs NPN Germanium? . . . low hFe vs high hFe. What would be a logical three of four different options that would be fun to try for a "variety of different tones"? My tastes lean toward "unpredictable audio chaos freakout" vs "smooth, lush and warm" fuzz. Having not done this before I'm curious to try out different things even if some might not be seen as the optimal choice for this circuit
. . . thanks for listenin' . . . if anyone still is after 7 years.
