Tsuchi Fuzz has a highly sensitive attack response. The stronger the dynamic the more pronounced the edginess becomes. A soft shine can be pushed into a smooth mushy fuzz-up.
"one of the classiest cases ever..." "...The Tsuchi Fuzz is built with all sorts of considerations and artistry (...) and it sounds pretty darned fantastic." "a lot of positive features and I honestly can't think of one negative one except maybe that it's not free" - Brett Kingman, world class pedal reviewer.

With four controls, you'll think of it as like many boutique fuzzes combined in one. The controls are dead simple though and it's nearly impossible to make a tone that isn't pleasing to the ear.

PRE-GAIN: The internal gain is fixed and a volume control is used at the very beginning of the circuit called "PRE-GAIN" to emulate rolling your guitar volume knob back. This controls the amount of fuzz. This has a better compatibility in more configurations.

BOTTOM: Most original fuzzes had a very heavily saturated bottom end. This usually sounds great but really limits the pedal to one tone and doesn't work well in every situation. The Tsuchi Fuzz has a bottom end taming control which both changed the bass response as well as giving more definition to the fuzz character. This is not a simple bass cut by using a smaller input or output capacitor like others do, which drops out all frequencies below a certain point, but rather a way of dialing bass down so that none of the original instrument frequencies are forever abandoned. This can also help out with using humbuckers and if you want a sound closer to single coil pickups or moving to the neck pickup for a smoother sound.

BIAS: There is an internal control on the circuit board to adjust bias. This should come and is used to balance the tone for a more spitty/splattery sound or to make it a smoother mushy sound.

VOLUME: Increased output means the Tsuchi Fuzz can deliver far beyond a unity gain.

All first generation transistor were PNP. Unlike other PNP fuzz faces, this one does not need to use it's own isolated or special kind of power supply. It simply uses the standard type and can be shared with other pedals.

A hand made circuit board layout has been developed with 1960's inspired artwork with rounded flowing copper tracks. This is made on a tanned paper-based board, not a modern fibre-glass. The copper traces are plated with tin after etching.

Current production standard models are made with:

Hand selected, matched and audited, new-old-stock, low leakage transistors.
Tropical fish capacitors.
Carbon composite resistors and potentiometers.
Paper-base circuit board material.
These components are only while still available in stock. In other words - until they are gone.
*As old parts are not consistently available, parts may be substituted to those shown in the photo. The photo is only an example of the build quality and quality of part kinds used. Even two of the same kind of germanium transistor usually will no respond that same way. As such all parts are tested, sorted and matched to make the circuit as intended. Most germanium transistors now left available are not suited to make the best sounding fuzzes. I will be going through all of my old stock and will change components to maintain a consistent sounding circuit. If you have specific requests for brands, numbers, gains etc. please contact me.
