Solid Gold FX Super Drive
Here's an interesting take on the classic DOD 250/MXR Distortion + circuit. It's pushed by a simple BJT boost and has an added presence control and tone switch. Schematic here. Easy to fit in a 1590B...

EHX Small Clone
The blog needs more modulation, so here's the classic EHX Small Clone chorus. Made famous by Kurt Cobain, the Small Clone has a wide range of chorus tones. I've laid it out two ways, one stock, and...

Solid Gold FX Rosie
Happy Fuzz Friday, all! Here's a cool silicon Tone Bender style fuzz from Solid Gold Fx. Aside from using silicon transistors, the first stage is a JFET. When the switch is closed it adds in a 4.7uF...

J. Rockett Tim Pierce Overdrive
Thought this one was interesting so I gave it a go. It's a fairly typical Rockett overdrive (.45 Caliber, Animal, Blue Note, etc.) with a fairly typical MOSFET boost (AMZ Booster, EQD Black Eye,...

Boss SG-1 Slow Gear
The Slow Gear emulates a guitarist riding the volume pot or a volume pedal, creating a swell effect. This will fit comfortably in a 1590B or 125B, though with the 1590B you'll probably want to wire...

Caroline Wave Cannon
Here's a very cool Rat variant now out of production. Fairly straight forward Rat with a variation of the Ruetz Mod, LEDs for clipping and a switch to toggle a feedback loop. On the original this is a...

Earthquaker Devices Hummingbird V2
New Year, might make Modulation Monday a thing. We'll see. Anyway, here's the EQD Hummingbird V2. It's derived from the Vox Repeat Percussion and now updated to use the 2N6027 in place of the obsolete...

DigiTech Bad Monkey
With all the recent talk and hype of the DigiTech Bad Monkey lately, and the sky rocketing prices of them on Reverb, a layout seemed to be in order. I used to gig with one of these and loved the Low...

Ross Phaser
Yes, Modulation Monday is back with the Ross Phaser. It's not for the feint of heart, but doesn't require any JFETs, matched or otherwise. Instead it uses OTAs with 3, LM13700N (one for the LFO, two...

EHX/JHS Lizard Queen
Happy Fuzz Friday everyone! You probably didn't miss this collaboration between Josh Scott and Mike Matthews, and because of the old school style of the big box version, it wasn't to hard to trace....

Sarno Earth Drive
This one's gotten a fair amount of hype over the years. It's essentially a Timmy without the bass control and a few different values. The IC and clipping diodes haven't been confirmed, other than 2...

Exar OD-2
Here's a fairly unique OD from the mid-nineties and the Polish pedal manufacture Exar Electronix. It's a soft clipping drive based around a simple discrete opamp topography. Originals have J113 JFETs,...

JPTR FX Silver Machine
Happy Fuzz Friday, folks! Stumbled across this one recently and looked cool. It's basically 2 SHOs in series pushing a Green Ringer. Schematic for reference. Should fit nicely in a 1590B. I've also a...

Greer Amps Black Mountian
Here's one of Greer's latest offerings. Seems like a simplified OCD circuit with some value changes and different clipping diodes. Schematic for reference. Easy fit in a 1590B.

1981 Inventions LVL
Here's the new boost from Matt Hoopes. Cornish buffer up front, so like the DRV, not a true bypass effect unless you want to wire it that way. Signal is then amplified by half of a 1458 op amp, and...

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:

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...

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...

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...

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...

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...

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...
