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.

Os Mutantes Fuzz

Got a request for this one and thought it'd be a good Fuzz Friday layout. It's got a fair amount of treble and grit on tap and should fit pretty easily in a 1590a. Schematic here.

Lovepedal Jubilee

Here's Lovepedal's Jubilee–pretty close circuit-wise to the Purple Plexi and Black Magic. Should be a pretty quick build. Note, if it sounds too dark, replace the 47nF cap with a 4.7nF cap. Schematic here.

VooDoo Lab MicroVibe

Here's the Micro Vibe from VooDoo Lab—aka, welcome to jumper city. Always seems to happen with vibe circuits, but this one will fit in a 125B quite nicely. Pretty standard adpation of the old Univibe with speed and intensity controls. Set the trimmer to 250Ω (and be careful if you adjust it since there's no protection/limiting resistor). Schematic can be found here.

zVex '59 Sound

zVex's new '59 Sound looks to emulate an overdrive '59 Fender Bassman amp and is essentially a tweaked Box of Rock. I've left out the boost section (which is essentially a SHO after this circuit), but can be easily added with the old SHO layout here on the blog.

Also, there's another installment of the DIYLC tutorial up on YouTube today. I actually am not using DIYLC all that much in it...

Jext Telez White Pedal

Here's a pretty cool one for Fuzz Friday–the Jext Telez White Pedal. It's a recreation of an onboard overdrive unit in a vintage Vox amp used by George Harrison in the late 60s. Schematic can be found here. Pots are board mounted and I've tweaked the Yoko switch to just be a toggle instead of a rotary like the originals, and it should fit nicely in a 125B.

Vertex Steel String

Here's a relatively new effect from Vertex–the Steel String Clean Drive. It's supposed to sound like a Dumble amp and is 2 muamps going into a BMP tone stack. Schematic can be found here.

More progress with the tutorial. Actually wrapping up the DIYLC portion before moving onto the Photoshop bits.

Baja SLO

Here's another one from Bajaman. It's a modified version of his AFD, but tuned to sound like a Soldano amp high gain channel. There are enough differences to necessitate a new board. More info here on FSB. Much like the AFD board, this one has the option for buffered bypass or true bypass. And the drilling template fore the AFD will work for the SLO as well.
