Members roundtree Posted February 17, 2013 Members Share Posted February 17, 2013 I came across what I'm assuming is a home made boost pedal. It was left behind by a musician at a gig. It's in a plain black metal housing and has a single switch and volume knob. It sounds like a completely clean boost. Which is nice because it should be a simple clean slate for me to start with. I've always wanted to build an effect pedal, especially a fuzz, this should be an easy way to start, I'm assuming. I want to tinker with it and turn it into a fuzz pedal, or maybe something tube screamer like. Can anyone point me in the right direction or give me some tips?

Members spentron Posted February 17, 2013 Members Share Posted February 17, 2013 Looks like a MXR Micro Amp. It even has a 56K resistor next to the IC (green-blue-etc.). A sort of fuzzy distortion could be done by increasing the gain a lot and adding a volume control to get it in control. For example, by changing that 56K to 1M. Its R4 in the schematic: http://www.schematicsunlimited.com/download.php?manu=MXR&file=mxr-m-133-micro-amp-pedal-schematic.pdf I would recommend at least as much, use its boost to overdrive another dirt or your amp more. Buy a pedal for what else you need many are cheap. Link to comment Share on other sites More sharing options...
