Today was one of those days where I felt like messing with a cheap, old pedal. In its stock form, the Metal Master pedal isn’t too bad, but there were a lot of key ingredients missing. The most important one was dynamics. With this mod, most of the dynamics were restored and some of the clean signal even comes through for a tighter sound. Also, it seems to me like some of the high-end was tamed. I think that this pedal is now somewhat use-able for a gritty, 60s’ type of fuzz tone. I’m not sure why they called it Metal Master to begin with since its sound resembled more of a fuzz. Anyway, here’s the mod for this pedal:
1. replace D9 with a 100k ohm resistor
2. replace D1 with a jumper wire
3. replace C3 to a .22uf capacitor
4. replace C5 to a 47uf capacitor.
That’s it! It’s a very simple mod but one thing you should always be careful with is over-heating. The track pads on this circuit board seem to be weak and can easily come off, so be careful. I hope you enjoy the “fuzz master” mod and as always, spread the word to other pedal junkies and musicians.
