The classic EHX designed Muff Fuzz from the 1960's. It doesn't sound much like a big muff to be honest, its a lower gain effect giving out lovely funky dirt tones.
The PCB hangs from the pot inside the enclosure, so its nice and secure in there. The PCB is nice and small.
This is a beginner level build.
This kit is supplied with a JP1590B enclosure. The one knobbed version.
This kit compares to the Muff Fuzz by EHX.
