Human Gear Animato
A Bass/Guitar distortion pedal made famous by Christopher Wolstenholme of Muse. For infos on this project check the original threads on DIY and FSB (If you build it for bass you should add a blend circuit to improve the sound)
LM13700 to CA3080 Conversion Board
A lot of older circuit designs (DynaComp, Ross Compressor, etc.) use the CA3080, which is now obsolete and rather expensive. The LM13700 is essentially two 3080s in one chip, and much more affordable. Here’s a conversion board to use the 13700 in place of the 3080. Use long header pins, mounted from the solder-side of … Read more
Mojo Hand Colossus Fuzz
Info about the original: ALL HAIL THE COLOSSUS!!! Unleashed on an unsuspecting public, the Colossus is THE be all end all Russian/Civil War Muff style fuzz. Ridiculously tweakable, insanely versatile, and packed with 10 tons of Colossal Mojo. Rich harmonic drenched chords, sweet singing leads, sludgy stoner goodness, filthy bluesy mcnasties, Pumpkin flavored raunch…you name … Read more
Seamoon Funk Machine
The Funk Machine is a filter effect that can be used on either bass or guitar (or synth, Rhodes, harmonica, etc). It’s also like an auto wah, given that the wah effect is controlled by the string attack of the player. Original units used 2, LM741 chips, but I’ve laid it out for an LM1458 … Read more
Madbean FatPants Jr.
Madbean’s 2015 version of his FatPants boost. No videos available at the moment.
Orpheum Fuzz
For #FuzzFriday, I give you the Orpheum Fuzz. There seems to be several versions of this circuit (germanium and silicon), but it’s essentially a FuzzRite. Since I’ve already done a FuzzRite layout, I thought I’d do a different one with onboard pots. It’s meant for use with silicon transistors, but you could use some NPN … Read more
Madbean Flabulanche / Snow Day Overdrive-Compressor
Here are Jon Patton’s original Snow Day Overdrive and Madbean’s modified version (Flabulanche). You can find all infos on Brian’s website: http://www.madbeanpedals.com/projects/Flabulanche/Flabulanche_2015.pdf Jon Patton’s video: – 2n5457s are biased around 12V.
BBE AM64 American Metal
Here’s the BBE AM64. While “Metal” is in its name, it seems more suited for heavier rock sounds. 70s metal at best. Nonetheless, it’s a very good sounding distortion box. The circuit is essentially a Guv’nor with soft clipping instead of hard, along with a DS-1 tone stack.
TubeSound Overdrive
Here’s a simple one-knob drive that’s ripe for modification. It uses an interesting combination of one NPN and one PNP silicon transistor stacked together. There are a few different values you can tweak to taste. Here’s a schematic for reference: The input capacitor (C1) could be increased for more bass. C2 could be increased to … Read more
