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.

Royal Albert Hall Bender

Happy Fuzz Friday everyone! Got a request for this one put forth on FSB. It's based on the ThroBak sTone Bender, which itself is just a straight clone of the Tone Bender Mk II Professional. The layout is setup for positive ground and PNP transistors. You can use a voltage inverter daughter board or flip any polarized components and use NPN transistors if you want to daisy chain this with other effects. Also, I added a 1k limiting resistor of the bias pot (far upper right side of the board) that may need to be adjusted to taste. Easy fit in a 1590B.

ThroBak Strange Master

Essentially a Rangemaster with a switch selecting the input cap (Hi/Lo) and another switch (Ge/Si) selecting between a germanium or silicon transistor. The bias pot helps to fine tune the bias (imagine that lol) differences between germanium and silicon modes. Other transistors can be used other than what's specified. Something in the 100-120 hFE range for the germanium and something around 250 hFE for the silicon. Schematic here.

Throbak Overdrive Boost

Pretty much a Colorsound Overdriver clone. Laid this out for a 125B (because of the dual footswitches) with board mounted pots. The boost footswitch bypasses the PreGain pot and only uses one side of a DPDT. Use the other side for LED wiring. If the off board wiring is confusing, check out the thread with the schematic here on FSB. The diagram is for a vero layout but the wiring is the same.
