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.

EarthQuaker Devices Talons

A while ago I laid this out for board mount 9mm pots at the request of someone on FSB. Always intended to modify that original layout for use with more common 16mm pots. Turns out it was easier to just lay it out fresh. Anyway, the Talons is a very versatile OD with an active 3-band EQ, and can run off +9v or +18v power supplies.

Crazy Tube Circuits Starlight

Here's the Starlight fuzz from Crazy Tube Circuits for Fuzz Friday. Much like the Ziggy Overdrive from Crazy Tube, it's a string of FET stages in a row, only with a lot more them (and also some MOSFETs as diodes thrown in). It's laid out for board mounted pots and designed to fit in a 125B with top mounted jacks.

Smallsound/Bigsound Sparkle Motion

Stumbled across this one on the old Smallsound/Bigsound blog. The Sparkle Motion is based on the classic Rangemaster treble boost, but with a lot of extra controls. Schematic and more info can be found here.

BBE Boosta Grande

The Boosta Grande is a simple opamp-based boost that's pretty similar to the MXR Micro Amp. Only differences being where the pot is in the circuit and component value changes. Offers up to +20dB of boost. Should fit in a 1590A if you don't board mount the pot.

FuzzHugger FX Algal Bloom

Here's another cool fuzz from FuzzHugger for Fuzz Friday. The Algal Bloom is transistor based with a wide range of tones, from mild overdrive to full on fuzz. It has the Gain and Level controls you'd expect, along with a Bloom control (expands the fuzz tone), Clean (blend), and Power (voltage sag), along with 2 toggle switches for more things to tweak. Originals have the Clean control internally, but who doesn't love more controls? It's laid out with board mounted pots to fit in a 125B enclosure with top mounted jacks.

Auto Swell

Someone showed me this circuit and it's a cool addition to this library. It's an old project from Electronics & Music Makers magazine and allows you to ramp up and down your volume. It's not a true-bypass pedal, but essentially an always-on boost that increases your volume when the momentary footswitch is pushed. More info and schematic can be found in these scans:

Black Arts Toneworks Black Forest

This is Black Arts' take on the Colorsound Overdriver. There are a few component value changes and 6 different caps on a 2 pole, 6 position rotary switch at the input. It's got a wide range of tones, and goes from boost to overdrive to fuzz. It's laid out for board mounted pots and would fit in a 1590B if it weren't for the rotary. If you wanted to skip the rotary and just use one input cap, just populate the capacitor you want and jumper its corresponding pad to the SwA pad.
