It’s red! It’s a focused ‘70s fuzzstortion machine!

Added controls for bias and tone (high pass filter). Lots of smooth sustain at standard settings. Some dark glitchy fuzz at extreme settings.

-2N2430 NPN germanium transistors.
-ERO, WIMA, and Philips capacitors
-PR02 resistors
-3-way Input cap switch
-Q3 bias control
-High-pass filter control

An absolute gnarly adaptation of the op amp BMP! Heritage Effects- Distortion Sustainer

A silicon transistor tone bender MKII on hand-staked turret board.

The PCB is from Amplified Parts, just flipped upside down and soldered on the wrong side!

A very loud, very raw muff variant! Home-etched board. A little of whatever I have lying around!

Vintage parts on a home etched board.

My latest Supa Proto has an external fuzz control (originals just had a fixed resistor setting the gain), some extra power filtering (big blue cap on the underside), and a coupling cap after the last transistor stage. The result is a beefy MKI Bender with a high-pass filter and a ridiculous amount of sustain that seems to morph texture as the notes endure. Truly inspiring to play!

NPN 2n2430 germanium transistors, PR02 resistors, Philips and Vishay caps, all wrapped up in a Gørva Design S90 enclosure.

An absolute monster of an MKI Bender! A large value input capacitor and no coupling capacitor after the last gain stage makes for one unruly fuzz! Remove the gain control(set to max internally)and add a high-pass filter?? Yes!

Marshall would replace the entire circuit with a modified MKII circuit with standard Level and Attack controls.

Carbon Composition resistors, Ero and TRW caps, and a voltage inverter for standard power supply.

Hammered Blue enclosure from Tayda. Vishay Pr02 resistors. PHILIPS BC caps. The tone control has a center detent, or click, which I enjoy for the controls I turn most often.
