Mini Muffin Fuzz 1590A Build

[petercan]

Just finished my 2nd build, the Pedal PCB MiniMuffin in a 1590A. I’m trying to build some fuzzes in these enclosures due to space on the board, and well, I have no fuzz pedals. Overall, came out nice.
Swapped the germanium 1N34As with 1N4148s to improve output level and kept the pot at A100k.
Every thing fit in fine and used low profile electrolytic caps for space. Next 1590A, I’ll definitely use open jacks.

My experience with this circuit is that it has no headroom so I am wondering if your silicone diode sub give it much more?

I mean, it does, but it’s the smallest amount. Still does improve the circuit IMO. Instead of leaving the pot cranked to 100%, I can get different sounds at 70% and 85% ish without it draining the overall output

It is very underpowered but glad you could get some headroom. I used a muffin crumb to boost volume. I will build another one soon and I might try to breadboard it first to see what I can tweak. Or I may add another crumb. Anyway, cool to see that you stuffed this in a 1590a.
