Boot-Leg Effectors Rock 'n Roll Party

Here's a very nice sounding British-style overdrive pedal from Boot-Leg Effects in Japan. It uses three-quarters of a TL074 quad op-amp, as well as germanium diodes (most likely 1N60s). Original units use an electrolytic 470n capacitor, but I've laid out the board for a film cap (though the PCB has pads for an electrolytic). I've also added a pull down resistor at the input and some extra power filtering. Here's a demo from another DIY builder.

    hi everybody!
    i have build the pcb version,and it works at the first time!
    ( i think you can mark it as verified!)
    i heard about a "tone switch?" in version 1.5. I think this is a tone bypass switch ( maby with a push pull pot) any idea how to realize that?
    anyway, a lot of thanks and compliments for your great work!!

    greetings from austria

      Thanks for verifying! I'm guessing the tone switch just sets the tone pot at a certain point. I'd just wire an SPST off lugs 1 and 2 of the tone pot. When the switch is open (off), the tone pot will work, when it's closed (on), it will bypass the pot completely.
