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.

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.

SolidGoldFx If 6 Was 9

Happy Fuzz Friday, everyone! Here's a nice little modded Fuzz Face from SolidGoldFx. The switch selects between input caps and the Bias pot adjusts the voltages to Q2. Other transistors can be used beside the BC183C in the original. As usual, sockets are your friends. Easy fit in a 1590B.

Earthquaker Devices Westwood

For the blog's 600th layout, here's a new one that didn't take long to get traced. Here's EQD's newest offering, the Westwood Translucent Drive Manipulator. Great for pushing your amp and giving a near clean boost. It features an active 2-band EQ and sounds great on bass as well as guitar.

AnalogMan Prince of Tone

Wanted to redo my old layout with board mounted pots. I've laid it out with the Presence control externally and the diodes on a DIP switch, though you could easily wire up an external toggle if you want. Should fit nicely in a 1590B. If you want the King of Tone, just but 2 in one box.

Run Off Groove Azabache

Not sure how/why I avoided laying this one out for so long. The Azabache is a great sounding overdrive that emulates classic Fender amps. Check out the ROG article on the circuit for more info, schematic and sound demos. Adjust the trimmers so there's 6v on the drain of Q1, and 5v on the drains of Q2-4. You should be able to squeeze it into a 1590B.

DBA Octave Clang

For Fuzz Friday here's the Octave Clang from Death By Audio. It's a transformer based octave fuzz utilizing a 741 opamp. Fairly low parts count and should fit in a 1590B.

Ross Compressor

Somehow I've not laid this classic out already, so here's the Ross Compressor. One of the most highly thought of (and therefore copied) compressors of all time. Should be an easy fit in a 1590B.

Earthquaker Devices Disaster Transport Jr.

Here's EQD's take on PT2399 delay. The most unique thing about it probably the use of a Big Muff-like tone stack. It will definitely fit best in a 125B with the board mounted pots, but if you use long leg board mounted pots and populate them from the component side it should fit in a 1590B. Schematic can be found here.

Rockett Animal

Another fun overdrive from Rockett, this time going for a Plexi sound. Think of it as the first half of a buffer-less Tube Screamer with an AMZ Stupidly Wonderful Tone Control 2. Here's the schematic for reference. Should be an easy fit in a 1590B.
