MI Audio Tube Zone
Here's the Tube Zone distortion from MI Audio. Original has 6 knobs with the Presence pot internally as a trimmer, but I know how you guys like to fiddle with knobs, and the layout was turning into a...

JHS Haunting Mids
The JHS Haunting Mids is an EQ circuit that controls the mid frequencies along with giving a 10dB clean boost. From the JHS site:The Mids and Sweep controls work very closely together so you can find...

Christine Oscillating Fuzz
Here's a fun noisemaker for Fuzz Friday. It's an oscillating fuzz built around a CD4049UBE hex inverter and has good range of noisy fuzz tones on tap. Schematic in here. Read that a B100k works better...

EHX Bassballs
Not sure I missed doing this one ages ago, but better late than never. The Bassballs is a classic envelope filter that's been a staple of Electro Harmonix's line up for a long time. Designed for bass,...

Greer Amps Lightspeed
Wondered about this one for a while (but always suspected it was YATS). The best way to describe the Lightspeed (that I can think of anyway) is it's kind of like a Timmy with the bass and treble...

Craig Anderton Tremolo
To say Craig Anderton's body of work is vast is probably an understatement. But within that body are several DIY classics, and this tremolo is no exception. This is a modified/updated version,...

MOSFET Pie
Stumbled across this Big Muff variation designed by Anders over on the Tagboard forum. Seemed like a cool design for Fuzz Friday. Here's what he had to say about it:Inspired by Skreddy Top Fuel and a...

Noah'sArk Distortion M
Not a lot out there on this one, but stumbled across the schematic over on FSB. Apparently it's another Marshall-in-a-box type. Sounds pretty good. Should fit nicely in a 1590B. The 1uF and 2.2uF caps...

Lighthaus
Someone requested the Openhaus which, to be honest upon pulling up the schematic, made my eyes glaze over. It's big. But I came across a stripped down version on Sabrotone and it felt much more doable....

MXR Custom Badass Modified OD
Here's another one I was surprised I hadn't drawn up before. Like the Custom Badass '78 Distortion, it's also based on an old Boss pedal—the SD-1. (Or I guess you could say it's a modified version of...

Royal Albert Hall Bender
Happy Fuzz Friday everyone! Got a request for this one put forth on FSB. It's based on the ThroBak sTone Bender, which itself is just a straight clone of the Tone Bender Mk II Professional. The layout...

Baja Reactor
This one was requested ages ago and I got halfway through laying it out, and then promptly forgot about it. It's a power amp/speaker cabinet simulator, emulating a SLO power amp and a couple different...

Barcus-Berry 3000A
Stumbled across this schematic on FSB. It's a buffer/EQ/preamp for peizo pickups, specifically all Barcus-Berry electret microphone systems. I figured most would be building this into an instrument and...

EQD Arrows
I traced this one a while back and created the Lawn Darts PCB over on the store from it. About time I made a perf and etch layout. If a Rangemaster and an Electra ever got together and had a baby, the...

Face-Bender
Got a request for this one for Fuzz Friday. The Tone Bender Mk.II Professional is essentially a Fuzz Face with an extra gain stage up front. The Fuzz-Bender basically puts the extra gain stage of the...

Baja AFD MkII
Gotten a couple requests for this one. Here's Bajaman's second take at his AFD circuit with a better frequency response than the first AFD. More info here on FSB. Should fit nicely in a 1590B.

Escobedo MOSFET Duende
Here's a simple MOSFET-based booster circuit that'd be a nice alternative to the SHO. Should fit in a 1590A. FYI, the 1N4739 diode in the layout is a 9.1v zener. Here's the schematic for reference.

Bass Direct Box
Got a request for the DI portion of the Hartke LH1000 bass amp. This is more or less that, but with a simplified power section. In the amp this runs off a bipolar 15 volt supply, but I would think it...

ProAnalog MkIII Fuzz
Here's a variation of the classic Tone Bender Mk II Professional from ProAnalog Devices. It uses PNP transistors, so you'll have to use either a battery or voltage inverter to daisy chain this with...

Buffalo Fx TD-X
This one's inspired by the BK Butler Tube Driver made famous by David Gilmour (and a few others). It does away with the tube and replaces it with solid state circuitry. It's essentially a RAT with soft...
