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.

Baja AFD

Here's a unique overdrive design by Bajaman over on FSB. You can build it with either a buffered bypass or true bypass. If using true bypass, omit the 1k resistor below the lower TL062, and the 1uF cap and 100k resistor connected to the BP Out pad. To wire for buffered bypass, connect the In pad to the input jack, the FX Out pad to lug 1 of the footswitch, lug 2 to the output jack, and the BP Out pad to lug 3. More info and schematic over on the FSB thread. Thanks to 287m for sharing his layout.



Also, the next episode of the DIYLC Tutorial is up on YouTube. Almost have a completed layout!

MultiCab Sim

Got a request for this one, designed by Daniel Schwartz. Seems to be a pretty versatile cabinet simulator. Might be handy to throw this in the same box as the Mini Amp from earlier this week. More info, schematic, etc here on DIYSB.



Also the next episode of the DIYLC tutorial is up on YouTube. Forgot to plug it in the post from Tuesday.

1 Watt Mini Amp

Here's a nice little solid state amp for headphone use or a small 4Ω speaker. Good candidate for a bench top amp for testing purposes. You can board mount the pot and it will fit in a 1590A just fine.

DOD Carcosa

Happy Fuzz Friday, everybody! Here's a new fuzz circuit from DOD. It's a cascaded transistor design offering a wide range of tones with tons of output. Should be an easy fit in a 1590B.

Run Off Groove Uno

I know I've mentioned this to a few people over the past year probably, but I've finally been able to get it edited. That's right, here's my tutorial on how I layout circuits in DIYLC... the first installment at least. The tutorial shows how I created today's layout–the Uno from Run Off Groove. It's a JFET amp emulator of the Boogie Mk I. For the schematic, demo and more info check out the Uno article.

Fenrir Distortion

Came across this schematic over on the Tagboard Forum and thought it'd be a good addition here. Heavy distortion tones on tap with some clipping options and a full 3-band EQ. Switch is a SPDT on/on.

Electro Harmonix LPB-1

Got a request to redo the LPB-1 with the pot board mounted. Can't say I'm opposed and it only took about 5 min to layout. :) Easy fit in a 1590A. If you want to make the Screaming Bird treble booster, replace the two 100nF caps with 3.3nF.
