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.

Wampler Ecstasy

Here's another great overdrive from Wampler, with a wide range of tones to choose from. It has a simple 2-band EQ and a DPDT (on-off-on) switch to go between smooth clipping, no clipping, and hard clipping.


  1. Ok, I've just finished it, I've done yet three times using different layouts, I had always the same issue, dark sound and the sweep of the tone control wasn't that good. But , this time I've used this layout (thanks mate) and used:
    33nF for the input cap
    47 pF across pins 6&7
    and !!! the most important thing:
    Plastic 100pF instead of ceramics (the original have the same)
    10K lin pot for tone pot (some original used C25K, so 10K lin characteristic is a big part of the C25K )
    Cheers from Algeria;)

    1. Cool. Thanks for your notes and for verifying!

  2. The cap 1uf is a polyester in the schemantic, help, here is a electroly

    1. In my experience you can't tell a real audible difference between capacitor types. An electro will work just fine there and it saves space. If you want to use a film or other type of capacitor there you can.
