Cloning pedals from circuit schematics?

    Inspired by my inability to find an original MuTron (and inability to pay for the expensive ones that turn up!) I figure why not just clone it. I found this circuit diagram online that I plan to clone:


    So, I know some beginner circuits (took an E&M physics class in college), plus I feel like it will be more like following directions/completing a puzzle anyway.

    Anyone do this? How difficult is it?
  2. Why not buy a clone kit? Fuzzdog does a Mutron circuit and even sells the right VCA's to make it sound right.

    +1 on the kit. A PCB and knowing what types of caps, pot tapers and other components will be worth the price of admission. If it's a complete kit, you might save some money. If you buy all the components separately, plus bread boarding stuff, board stand offs, soldering stuff, and a good box to use as a pedal, maybe not and might never work. I used to build prototype circuits, more or less complex. I enjoyed the work, but unlikely I would do much without getting paid.

    Google DIY pedals. There's a good forum and blogs. Check allelectronics for a good, cheap variable temperature iron + stand. I have good expensive irons, but usually go for the $20 iron because I rarely sit and solder at a bench these days. I might go for on of these next time I order something: TEMPERATURE-CONTROLLED SOLDER STATION 50W If you do need components, they are a pretty good go to if they have what you need (surplus, limited selection). Knobs, switches, a box and bread board they have covered.

    It's kind of amazing that that's all that's inside a Mutron III. Then again, I suppose that's why other companies could build envelope-controlled filters into enclosures one-third the size of an original Musitronics!

    Incidentally, I've had some work done by CJLectronics, he's one of the good guys when it comes to salvaging your irreplaceable vintage stompboxes.
