This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

MXR Distortion II

This one was kind of a sleeper. No where near as popular as MXR's Distortion +,  the Distortion II was quite a bit more complicated and ran off a 15v supply, complete with a built power cord . This layout is a bit modified from the original, and can be run off a normal pedal power supply (+9/18v). Originals also tend to be very bass heavy, so I've included a few mods to tame the low end. You might be able to fit in a 1590B, but a 125B will have a bit more room.

      Usually the input or output caps. So try to rise the 100nF in the bottom left corner.

      Those are the points to wire in power, yes. If you're doing a battery snap, you'll need to wire the negative lead to a stereo jack. Google how to wire in a battery snap–tons of illustrations online.

    I finished this device, works preety well! I think this layout can be signed as verified.
    Used 33n caps instead of 35n, 47p caps instead of 50p and 914 diodes instead of 4148.

      No sabes hacer pedales entonces.
      Seguramente escogiste componentes de mala calidad, baratos y muy probable no mediste ningun valor. El pedal suena genial, el error es tuyo...

    Sounds great! But replace the bias resistor to 10k to get that original feeling of mxr dist 2
