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.

Roland AF-60 BeeGee

Happy Fuzz Friday, all. Somehow in 10 years of laying out fuzzes, I've never done this one. Here's the  Roland (pre-Boss) AF-60 BeeGee fuzz. Originals use semiconductors you probably don't have in your parts stash, but nothing in mojo territory, so modern equivalents will work just as well. Fairly simple circuit with a couple transistor amplifiers, an opamp stage, hard clipping, and a BMP-style tone stack. Here's the schematic for reference. Easy fit in a 1590B. (Transfer image in the Boss folder)

Earthquaker Devices Disaster Transport

 I traced this one a while back. It's the same delay circuit as the Disaster Transport Jr but with modulation added. It fits nicely in a 1590BB like the original. Schematic here




If you'd rather a smaller footprint I have fabricated boards for a 125B in the store.

Marshall Shredmaster

 Here's another old layout redone for all you Jonny Greenwood fans. I think the old layout was based on an old and incorrect schematic (here's the schematic used for this layout), but this one should be right and a much easier fit in an enclosure than the old one.

Roger Mayer Axis Fuzz

For Fuzz Friday here's the Roger Mayer Axis Fuzz redone with board mounted pots. Schematic for reference. Didn't make a drill template for this one, but the pots are 1.2" apart and should be an east fit in a 1590B.

Aleph Null Special Sauce

 I'm a big fan of Brian's, aka Aleph Null's, circuit designs he's been kind enough to share over on the MadBean forum. Here's one of his latest offerings, the Special Sauce. In his own words, "It's a short delay with envelop control pitch bending. This makes for unique chorus, doubling, slap back, and vibrato effects." More info here.

Reeves Electro Zo:

Stumbled across this one I though would be a quick Fuzz Friday layout. It's a modified Zonk 2 with silicon transistors. Originals use NOS 2N3416, but other low hFe (150-200) BJTs should work just fine (2N2222, 2N5550, etc). Laid it out so the board would be vertical in the enclosure with the pots attaching to either side of the board. Schematic for reference.

Black Cat OD-1

 Did this one quite a while ago, but wanted to redo some of the old layouts with board mounted pots. The schematic online has the topology correct but the 100nF caps are 47nF from the gut shots I've seen, so that's reflected below. Might be good to socket and experiment with.

EQD Fuzz Master General

 Happy Fuzz Friday! Here's a Univox Super Fuzz derived circuit from Earthquaker. Should squeeze into a 1590B just fine. Here's the schematic for reference:
