Maestro Bass Brassmaster
The Brassmaster was originally designed for bass and also picked up by guitarists. The circuit is very unique and originals are hard to come by. I was able to lay it out to fit in a 125B with board...

EWS Little Brute Drive
Found this one on FSB and haven't seen any layouts for it, so I thought I'd give it a go. Originals are in 1590A enclosures with the Tone and Volume controls as trimmers, but I've laid them out as...

GodCity Brutalist Jr
Here's a really cool distortion based on Providence Stampede and designed by Kurt Ballou of GodCity Studio. He's actually made his business card a PCB you can build this circuit on, and if you can...

Mid-Fi Electronics Pitch Pirate
Here's the Pitch Pirate with board mounted parts. Like the Deluxe version, the LFO is designed to be grounded when the effect is turned on (hence the pad at the top of the board). Just use the...

Lumpy's Tone Shop Lemon Drop/ZII/Series 7
Here's a simple little overdrive designed to emulate the old Vox 4 and 7 series amps (used by the likes of Jimmy Page and the Beatles). Pots are board mounted and it should fit in a 1590B easily. I've...

Wampler Tweed '57
Here's another (and more complicated) amp emulator, and another great design from Brian Wampler. This one stacks JFET stages much like the Cranked AC. It emulates a dirty Fender tube amp with a 3-band...

SMD to Through-Hole Conversion
There are a lot of circuits (a lot) that use J201/2N5457 JFETs. Sadly, these components in the TO-92 package are out of production, and many of those that can be found online are either barely within...

BJFE Folk Fuzz 3.5%
For Fuzz Friday, here's a great fuzz design by Bjorn he did for the DIY community. Q1-2 can be either silicon or germanium, and Q3-4 are used as clipping diodes. Here's the schematic for reference....

Way Huge Purple Platypus
Here's a bit of a rarer old school Way Huge circuit from the 90s. It's essentially what would happen if a Red Llama and a Foxx Tone Machine had a baby. Original thread on FSB here with schematic.

Nocentelli JFET Boost
Here's a recent design by Nocentelli. A single JFET stage into a Baxandall EQ stage with a BJT gain recovery stage. Originally designed with an opamp gain recovery stage and no gain control, Nocentelli...

Landgraff Dynamic Overdrive/Clay Jones Overdrive
Probably two of the most hyped Tube Screamer clones around. The only real difference between the Dynamic Overdrive and a TS808 is the clipping switch, offering symmetrical red LEDs, diode lift, and...

Chunk Systems Brown Dog
Got a bass fuzz for Fuzz Friday this week. It's a gated fuzz with both clean and dirty level controls, an envelope jack to use with funk-style effects, and a soft/hard clipping switch. From the...

Earthquaker Devices Palisades
The mother of all TS808 derivatives/variants, the Palisades incorporates just about every mod to the classic Tube Screamer circuit. Two rotary switches control the bass response (Bandwidth) and...

Skippy Tremolo
This is Moosapotamus' take on the Vox Repeat Percussion tremolo. The Skippy keeps the character of the original, but with more control while covering a much wider range of tones. There's also the...

Wampler Hot Wired V1
The Hot Wired is a dual channel dirt box offering distortion and overdrive modeled after the tones used by Nashville session artist Brent Mason. I've laid it out for board mounted pots with the board...

Dwarfcraft Great Destroyer
Here's a fun sputtery beast for Fuzz Friday. Like many of Dwarfcraft offerings, this ones got a lot of character and goes from fuzz to experimental with just a few knob turns. I've laid it out so you...

Spaceman Effects Saturn V
Here's the Spaceman Saturn V boost pedal. It's a pretty unique booster and uses depletion mode LND150N3-G MOSFETs. In original units, there are 2 resistors in series going to each drain of the...

BearFoot FX Baby Blue OD
Here's Bjorn's Baby Blue overdrive. Fairly straight forward JFET circuit with hard clipping in the 2nd stage. The clipping diodes in the original are (massive) 2A1200s, but other silicon diodes will...
