EarthQuaker Devices Talons

The Talons is a great sounding overdrive pedal and is EQD's take on the Marshall Guv'nor. FSB member Zedsnotdead traced it and requested a layout with board-mounted 9mm pots to fit in a 1590B. As per usual, the pots should be mounted on the solder-side of the board. Watch out for the EQ pots as they are oriented 180º differently from the top row of pots. The in and out pads ended up in a bit of a weird spot, but shouldn't be an issue. (You'll just have to use a little more wire to get to the footswitch.)

EarthQuaker Devices White Light

The White Light is based on the MXR Distortion +/DOD 250 circuit, but with some modernization and improvements. There's an added tone control called "Weight" and the toggle switch adds compression by adding an extra germanium clipping stage. The board is laid out for solder-side mounted right angle PCB pots or you could use long leg right angle PCB pots and mount them from the component side of the board.

The Rocket

The Rocket is Aron Nelson's modified version of Gus Smalley's 3 Transistor Fuzz. Basically it's a Fuzz Face with an emitter follower in front of it. Just about any medium to high gain transistor will work. Not a bad idea to socket some of the capacitors and try different values (see Aron's schematic and notes for more info). The pots are meant to be mounted on board from the solder side with the board perpendicular to the bottom of the pots. Also, I tried something a little different with the PCB layout. I think it's a little more professional looking and should use less etchant, tho maybe a bit more printer toner.

AMZ Dr. Quack

The Dr. Quack is Jack Orman's improvement on the EHX Dr. Q envelope filter. Basically, there's an added input buffer to increase the input impedance (which is kinda low in the Dr. Q) and offers better range control. Check out Jack's blog post on the circuit for more information and a few mods.

Mad Professor Deep Blue Delay

The Mad Professor Deep Blue Delay is regarded as one of the best PT2399 based delays out there (with the price tag to match that reputation). It's a warm and natural sounding circuit with an analog direct signal path (aka, no buffers), and plays nice with distortion boxes as well. I've labeled IC1 as a TL072 as it's what you most likely have in your parts drawer, but the originals have either OP275 or AD712 for what it's worth. Pots can be board-mounted from the solder side of the board using right angle PCB mount pots.

AstroTone Fuzz/Sam Ash Fuzzz Boxx

Here's a quick one. Fairly simple silicon fuzz from the 60s. AstroTone marketed these under their own name, as well as making them for Sam Ash. I laid this one out so the board mounted pots are in a triangular layout. The Attack and Volume controls are mounted on the component side, while the Tone control is mounted on the solder side like this:

Dirty Boots Overdrive

Found the schematic for this over in the Aron Nelson Gallery. It's designed by Scott Frein. Uses a simple JFET buffer to help push the transistor-based drive section. Here's his description:

A pretty simple overdireve. The buffer on the front really brings it to life. Good AC/DC,ZZ Top crunch from this. Hit it with a booster and go from JCM 800 to Fuzz.
