Ramble FX Marvel Drive 2/3
Here's a newer version of the Marvel Drive from Ramble FX. Did the first version of this circuit a couple years ago, and decided to update the layout with board mounted pots and the Presence pot. I...

Devi Ever Dark Boost
Haven't done a Devi circuit in a while, and I keep stumbling across them, so here's the Dark Boost. It's essentially an Electra circuit without the clipping diodes and a Pre-Gain control. Apparently...

Sunn 200S Preamp
Here's a simple bass preamp circuit derived from the Sunn 200S using JFETs. It's pretty similar to the Bassman Preamp, but with the EQ section at the end of the circuit instead of the middle. Original...

Devi Ever Ruby
Here's another Devi circuit for Fuzz Friday–the Ruby. It's essentially 2 Electras (sans clipping diodes) stacked. In Devi's own words, "The Ruby is like a Tone Bender, but way classier and secretly...

AMZ Overdrive Pro
An oldie, but a goodie (I assume–Jack designs good stuff). It's a unique high gain design with a 3-band EQ. In Jack's own words:It was made by combining the following circuit fragments: input gain...

MXR Micro Chorus
The originals used a now nearly unobtainable SAD512D chip, but the wizards on FSB converted it to work with an MN3007. Now that those are also hard to get a hold of, I've laid this out for an MN...

Eazius Tremor
Stumbled across this schematic and it's like CJ's Shoot the Moon and the EA Tremolo had a baby (Though I think this predates the Shoot the Moon...)–the audio path is like the Shoot the Moon and the LFO...

Basic Audio Spooky Tooth
Found a trace of this over on the Tagboard Forum. It appears to be a highly modified Fuzzrite with an added gain recovery stage and a lot of value changes. The Saturation pot increases the output cap...

Budda Om Overdrive
Stumbled across this one and it seems pretty cool. It's like an Escobedo Punch-in-the-Face sandwiched between two opamp gain stages, and is very similar to the Carl Martin Crush Zone. Wide range of...

Baja AC30TB Emulator
Another one of Bajaman's many amp emulator circuits. It emulates the frequency response of the classic Vox AC30 top boost channel, including power amplifier emulation. It's designed to fit in a 125B...

Bajaman AC30 Normal Channel
Here's Baja's AC30 Normal Channel emulator. Throw a treble booster in front of this and you're pretty darn close to nailing some Brian May tones. Schematic and discussion here on FSB.

Hughes & Kettner Red Box Mk. II
Here's a nice utility box for home recording or even live application (if you've run into a sound guy who hates guitar amps 😠). It's a direct box but also a cab sim (4x12). It won't run off phantom...

Rockett .45 Caliber
Here's the .45 Caliber overdrive from J. Rockett Audio Designs. It's essentially a simplified Timmy without the second opamp stage, and claims to emulate the sound and feel of a 1962 JTM 45. Easy fit...

Basic Audio Pep Fuzz
Here's another one from Basic Audio for Fuzz Friday. This is John's take on the Wem Pep Box and adds variable output cap control with the Body control. Should be an easy fit in a 1590B. Here's the...

Ibanez FC10 Fat Cat Distortion
Got a request for this one, it's a good addition to the collection. It's Ibanez's take on the RAT in their Power Series from the mid-late 80s. It's very similar to the LM7 LA Metal circuit, with just a...

Run Off Groove Tri-Vibe
This is (or was now I guess) one of the few Run Off Groove designs I haven't laid out. It's not a small circuit and I ended up laying it out for a 1590BB so the pots can be board mounted (but it will...

Demedash Effects Incandenza Bypass

Buttercup Fuzz
Stumbled across this one on FSB and thought it looked cool. It was designed by JD Barbato and is kind of a mashup between a Tone Bender MkII and a MkIII, with a BMP-style tonestack, with a switch...
