Germanium amplifier v2

This is my attempt to make the world's best germanium boost pedal. The range is set for my personal 'sweet spot' for full body, but can be custom altered for treble, mid, or full cream operation on request. An internal switch can be added to switch between any two range modes.

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 his 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 clean 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.

The Big Fuzz is a muff circuit, which has been made to factor all of my favourite elements from the many various models. Further, some improvements have been made to improve user interaction. This includes increased bass, and improved bass clipping response, improved tone control functionality, and fine tuned top-end clipping response and smoothing.

The classic design varied greatly over the years, being made in various locations to different schematics and ever-changing component values. One large reason I suspect some models are still higher favoured now, is for their amount of mid-scoop. This is a famous love-hate element of the circuit. However, having this second tone knob adjustment is incredibly helpful.

There is an internal mod switch to change for a huge-bodied bass response, as well as switches to change the gain stages to match different models.

Tremolos interest me as a good design has its own lively pulse, which can sound lively like the instrument itself.

By shining a fading light against a photo-sensitive device, this tremolo uses all analog photo-coupling to restrict and fluctuate the output volume. After a decade of development, I've created this completely unique circuit, as my ideal tremolo sound.

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

Presently, only black+gold version is available until I make some more white version enclosures.

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.

I had been reluctant to join the tube screamer cloners, but over the years I’d assisted in many custom overdrive designs and I feel it was time to settle this.

The modules are switchable in easy-to-use combinations, aiming to deliver to many pickup selections, gain settings, and play styles. No need to mess with the classics though. In “3 knobs” STD mode you have a stock 808 circuit. “2 knobs” switches to an OD1 tone stack.

The mods switch has modes for fatter bass, and asymmetric clipping which closer resembles tube clipping. All capacitors are expensive mojo tone caps, selected for a sweeter response curve.
