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.

Emanating Fist XB-70

The XB-70 is a clone of the Captain's personal '77(?) Guild Foxy Lady, which were built by Electro Harmonix and generally very similar to Ram's Head Big Muffs. In the Captain's own words, "It sounds like torn leather soaked in piss and salt smushed lovingly into ears... It is a brute of a pedal, has a really intense roar at full tilt, like any good Big Muff really." I used my old Ram's Head layout as the starting point, but altered the pot placement and it should be a nice fit in a 125B now.

  2. Is the trace side inversion correct? Doesn't look flipped.

    1. The trace side is correct. You don't need to flip it.

  3. It worked first, I used all the same values, the transistors tried the BC239C. The sound is spectacular, the layout is perfect. Thank you so much!!!
