Electro Harmonix Freedom Preamp Pedal
Here we have a rare bird from the early-mid 70s. A tweaked version of the the circuit found in Freedam Preamp amp found its way into some Big Muff enclosures. Original is very pricey and rare. The original ran on two 9v batteries for bipolar power supply for the op amp section but I added … Read more
Madbean Rump Roast
Another old request. An old old forgotten madbean circuit which is based on the preamp section of Dr Z Carmen Ghia.
DOD FX33 Buzz Box
This one have been requested a few times. Factory schematic had a few bugs (as with most DODs) so this layout is based on the schematic by Griffin Fx for their Buzz King project.
Black Effects Pedals Dry Line Driver
Another great tracing (and de gooping) work by Tobias. This one is supoosed to be a heavier version of a Colorsound Overdriver with an added “Contour” diode control for more fuzz on tap.
Wyllie Moonrock
One of the more innovative fuzz designs out there. This is a quite a crazy octave up fuzz in the vein of Octavia and Scrambler with the Offset control dialed up. Roll it back for less octave and a pronounced swell effect.
Black Effects Pedals Fuzzawe
Another trace by Tobias. This one is based on ROG Whisker Biscuit but with larger input, coupling and Miller caps. Also, the tonestack has been modified for a wider range.
Black Effect Pedals Lava Machine

They were producing mostly fuzzes on the heavier end of the scale, suited for doom and stoner toanz. Lava Machine is based on Univox Unidrive with some tweaks and addons. Two onboard trimpots to tune … Read more
Fjord Fuzz Berserk V1
Another interesting Fjord Fuzz circuit traced by evilarsen. An old school silicon fuzz with a switch that toggles between Fuzz Face/Tonebender Mk. II modes. Also a thickness pot that is a input cap blend control. It may be worth having the internal bias trimmer as an external control…
