Bass Filter Pedal
Here's a cool little bass filter pedal designed by bleepboxes. Really low parts count should make for a pretty quick build. Original info here. Might be a good idea to put the 4.7n cap on a switch with...

Way Huge Tone Leper
This is a rare one from the early 90s from Way Huge and is based on the Craig Anderton Frequency Booster. Stock it gives a mid range boost (800Hz), but that frequency can be altered by swapping the 2,...

HomeBrew Electronics Detox EQ
Here's and interesting 3-band EQ from HomeBrew Electronics. They say it's like adding a second channel to your amp, cleaning up a dirty signal with the level turned down. Think the opposite of an...

ThroBak Strange Master
Essentially a Rangemaster with a switch selecting the input cap (Hi/Lo) and another switch (Ge/Si) selecting between a germanium or silicon transistor. The bias pot helps to fine tune the bias (imagine...

EWS Tri-Logic Bass Preamp II
Here's a pretty simple but effective bass preamp from EWS. It's a 3-band EQ being pushed by a MOSFET gain stage. Looks like EWS made a version for Xotic with the same name. Not a lot different between...

Keeley Rotten Apple
Happy Fuzz Friday, everyone! Here's another one of Robert Keeley's takes on the IC Big Muff with a quad opamp (the other being the Psi Fuzz). Pots are board mounted and it should fit into a 1590B.

BearFoot FX Model G
Today's layout is the Model G from Bjorn. It's a variation of the Honey Bee and aims to replicate the sounds of some classic Gibson amps from the 50s and 60s. Board mounted pots and should be an easy...

Bearfoot Model H
Keeping it in alphabetical order, here's Bjorn's Model H. Similar to the Model G, but without the the "C" pot and a few value changes, it emulates the Hiwatt amps Pete Townsend used on Live at Leeds....

Inverting Phase Buffer
Got a request for a dual buffer that inverted the phase of the signal. Found this post from Parasit Studio and used it for the basis of this design. I added polarity protection, power filter cap, and...

zVex Machine
Happy Fuzz Friday! Not sure how I haven't laid this one out before. Think of it like a mashup of a SHO and Tim Escobedo's Tripple Fuzz, and then repeated. Here's the schematic for reference. This one...

Lovepedal Zendrive 2
The Zendrive 2 is a big box version of the Zendrive, using a 12AX7 internally. Sadly the tube is only being used for clipping, replacing the BAT41 and 1N34a diodes in the small box Zendrive. But...

Square Wave Oscillator
Came across this Instructable the other day and thought it would be a good addition to the library. Would be a good first step into the synth world and apparently plays nice with guitar pedals. Already...

Menatone Ms. Foxy Brown
Another Marshall-in-a-box, the Ms. Foxy Brown uses 3 J201s and feels a lot like an older Run Off Groove design (though it's not). As per usual, you'll need to bias the J201s to about 4.5v and then fine...

Korg DST-1/Yamaha DI-01 Distortion

May I?
Got a request for this one. Another AC30/Rangemaster emulator to try and get Brian May's tone. Here's the schematic for reference. It calls for "BC245/256" JFETs for Q3-4, but I think that's a typo and...

Keeley 1962
Take a Blues Breaker and mash it between two Katana boosts and you have the 1962. Couple minor differences from a typical Blues Breaker beyond that. Trace over on FSB. There are two versions of this...
