RAD DISTORTION

This is my attempt to reshape classic ratty sounding distortion form the '80 and '90s.

A distortion unit with two voicing modes. 'SI' silicon mode is the classic sound. This is achieved by a two-stage distortion of first overdriving the operational amplifier chip into a metallic fuzz, and then compressing the signal using hard-clipping silicon diodes.

In the 'GE' germanium mode, the op amp fuzz has been removed. Germanium transistors and four germanium diodes are used to achieve a more rounded and organic overdrive-distortion. This works well with humbuckers where the gain is driven a little more.

There is an internal trimpot to dial the mid/high saturation to suit your pickup and style - only if you feel the need to fiddle. Turning this completely right achieves the 'stock' ratty distortion. Turning this left achieves a more flattened and bassier response, which can be well suited for the germanium mode.

All of the active signal processing is handled by parts wrapped in either metal or glass - all mojo. These components are in limited availability, and likely will be subject to change in the future as this project continues.

Special components:

• Authentic NOS LM308 Metal can operational amplifier IC.
• AC128 germanium transistors.
• Telefunken black glass silicon clipping diodes.
• Germanium clipping diodes.
• Nichicon film capacitors.
• Panasonic electrolytic capacitors.
• Dale Industrial grade precision metal film resistors (1%, 100 PPM / C).
• 600V Teflon wiring.
• Switchcraft audio sockets, Hammond enclosure. Usual stuff.

The Tsuchi Fuzz V2 takes a new look at the classic two-transistor fuzz circuit. The circuit’s tone has been carefully evaluated at every shaping point, to produce either classic or modern fuzz tones.

Components used may vary slightly over time to those shown in the photo, due to stock availability - particularly transistors. Photos are shown only as a general illustration of construction and components quality.

Germanium amplifier v2

This is my attempt to make the world's best germanium boost pedal. An internal switch can be added to switch between any two range modes.

Internal tone switch options:

Mid / Full range Treble / Mid range Treble / Full range

Here's my take on a muff based fuzz-distortion. This has some unique mods which I believe dramatically improve the tone and playability of the pedal.

There is an internal dip switch for bass friendly mode with an enormous bottom end response.

This circuit (Brown Sound in a Box 2) was by far my favourite distortion back in high school. The cool thing was, if you wanted one, you just have to build one or know somebody who could. The circuit was designed by Ed Guidry, similar to works by Jack Oran and Aron Nelson. Back in the day, it was one of the highest recommended builds on the forums. Many would suggest that this design was the original precursor to many of the "high gain amp" pedals that came out in the 2000's. It's basically a Marshall stack tone faker.

It has a tonne of gain, and a huge bottom end to fake a big amp. My build also has improved noise spec. This circuit also responds excellently to rolling back the instrument volume knob.

Distortion is achieved by overdriving Fairchild field effect transistors (FETs), being the closest solid-state relative to vacuum tubes. No diodes are involved for clipping. There are three stacked gain stages. The first two are μAmp stages, which is a classic valve topology developed to achieve high gain performance from tubes. The final is a class a stage.
