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.

The BIAS knob controls how coarse or smooth the breakup character of the fuzz is.

The CUT knob shapes the bottom-end at the input of the circuit. This can make the fuzz start to behave more like a fuzz-distortion. The BASS EXPANDER switch can compensate for the removed bass in post-EQ. These two controls can be useful to have the fuzz sound stand on its own without having to drive a later sustain stage in your signal path.

All units are made to order, and can take up to a week to be posted.

RAD DISTORTION

This is my attempt to improve everything that I didn't like about the classic ratty sounding distortion form the '80 and '90s.

A distortion unit with two voicing modes. 'SI' silicon mode is the classic stock 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.

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 response, better suited for bass.

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

Special components:

• Metal can operational amplifier IC.
• AC128 germanium transistors.
• Germanium diodes.
• Telefunken black glass silicon diodes.
• Nichicon film capacitors 5% tolerance.
• Panasonic electrolytic capacitors.
• Dale Industrial grade precision metal film resistors (1%, 100 PPM / C).
• 600V Teflon wiring.
• Switchcraft audio sockets, Hammond enclosure, CIC footswitch. Usual stuff.

The Fairchild Korean 308 chips are now exhausted and not available any longer. I am continuing production with Motorola LM308AH. They do not dissapoint (to say the least).

PROFESSIONAL DRIVE

This overdrive circuit has three voicing modes, which may better suit different pickups and play styles:

• SYM - Symmetrical clipping is a classic 808 overdrive, with no mods. This mode has the most amount of clipping.
  
• ASYM - Asymmetrical clipping begins to ‘look’ more like a valve amplifier clipping. This can better suit input signals which already have a full bottom-end, such as bridge pickups, and allows chords to better shine through.
  
• FAT - Also asymmetrical clipping, but with a fuller bottom-end output. This is helpful to use the pedal more for its own distortion, rather than pushing a drive channel into further clipping.

The gain control has twice the gain range than you would expect from a classic TS.

This circuit was made using the following special components:

• Nichicon film capacitors 5% tolerance.
• Panasonic electrolytic capacitors.
• Dale Industrial grade precision metal film resistors (1%, 100 PPM / C).
• 600V Teflon wiring.
• Switchcraft audio sockets, Hammond enclosure, CIC footswitch. Usual stuff.

Please note that this model does not include the extra "2 knob" tone knob shown in previous demonstration videos.

CLASS A

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.

Components used may vary slightly over time to those shown in the photo due to stock availability.

Internal tone switch options:

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

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.

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.

Tremolos interest me, as a good design has its own pulse, which can sound lively like the instrument itself. This was my first effect design which I started in high school. I *thought* it would be simple enough to build an effect which only needs to make the volume go up and down. Well, not quite so. After a decade of development, I've created this completely original circuit, as my ideal tremolo sound.

By shining a fading light against a photo-sensitive device, this tremolo uses all analog photo-coupling to restrict and fluctuate the output volume.

Always use a high quality regulated and isolated power supply for best operation. Daisy chain power cables may induce clock noise. A line level headroom optimised version can be made on request.

This is my attempt to make a perfect tremolo sound. After a decade of development, I've created this completely unique circuit as my ideal tremolo.

By shining a fading light against a photo-sensitive device, this tremolo uses all analog photo-coupling to restrict and fluctuate the output volume.

This is a stereo variation of my smaller Optical Tremolo. It can take a stereo input, or split a mono guitar input between two amplifiers. The PAN switch changes the oscillator of each channel to be out of sync - so one comes up in volume while the other drops. This creates a strange swirling effect. All original analog circuitry and true bypass mechanical switching.

Always use a high quality regulated and isolated power supply for best operation.

Please note that the GND lift switch is no longer used, which was previously seen on old demo videos.
