Custom “Fuzz Monster” Pedal

I’ve had my eye’s on a Electro-Harmonix Big Muff Fuzz pedal for some time now. It is the quintessential fuzz pedal for rock from the 60’s to today. One of the great things about being such a famous piece of gear is so many people have opened it up and played with the guts to mod their own style out of it. There are hundreds of pages of mods for the big muff you can find just by googling and you can find specs for any version whether you have a Little Big Muff like me or the full size one, Russian, Rams Head, Triangle or any mod already.

For mine I wanted to switch out three main things after doing a ton of research on the different tones. I love the Muff when it’s at about 10 o’clock Sustain. When you start to turn it up it has a tendency to get much more bass heavy and give a harsh shelf from speaker cracklin’ mud to a hissy, high rev engine sound. I decided to replace a few resistors and transistors to change my gain level and most importantly quiet the noise that comes from such a boost. It took a good 3 and a half hours to do but I finally got it modified and plugged in and I am really impressed by it. I still have the standard Pink Floyd round tubey bell like sustain when it’s from 7-9, a thick hippy fuzz around the 12 o’clock setting and now a killer ballsy metal chug when I crank it to 10. It’s definitely worth playing around with since the main pedal is only $70 and you can find all the replacement parts online for about $18.

  • Swapped out Resistors to get more gain
  • Added a trimpot to quiet all that noise
  • Swapped out to BC549 transistors to get more of a chainsaw sustain
  • Most importantly, add a Bitchin’ paint job!
