The Legend of Fuzz arrived today. This is the newer version with gold powdercoat and far superior build quality.
Just wrapped up the trace, so here we go.
There a few minor differences in this particular version of the pedal;
1) Both pots are A100K
2) The Control pot is wired backwards compared to the older version
3) As you can see in the pic below, the 2N2222A is a TO-92 plastic transistor instead of TO-18 metal can.
Everything else is identical to the Hylian Fuzz.
Using an audio taper pot wired backwards is similar to using a reverse log taper so it reduces the dead spot when turning the Control pot all the way down (or Up in this particular pedal).... the original does go almost completely gated.
The pedal sounds and behaves basically the same as my Hylian Fuzz build... which if I'm being honest, is just not very good.... but to each their own.
So to recap, here are the changes I'd recommend:
1) Install the 2N2907A backwards (the silkscreen on the PCB is incorrect)
2) Use a C100K pot for Control (equivalent to A100K wired backwards)
3) Use an A100K pot for Volume
I tried the circuit with and without the reverse polarity protection diode and filter cap, there was no audible difference either way.
I pulled all of the transistors and checked the hfe for those who might want to know.
Q1 - 795
Q2 - 205
Q3 - 821
Q4 - 805
Q5 - 798
Q6 - 128
Aside from that, I'm afraid that really is just how this thing behaves.
