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. It started from scratch, to be completely unique and not sound like any other existing tremolo circuit. Development took over a decade before I was happy with it.

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

The modulation waveform is asymmetrical in ascent and descent, in both shape, and time. I find this helps to not try to play in-time with the effect, and let it find its own timing over your signal. This was a characteristic of the spinning liquid can tremolos. The square wave mode is also asymmetrical - it stays in the 'on' state a little longer than the 'off' state, which I think sounds much better.

As with all of my tremolo models, you should expected perceived unity volume with all depth and rate settings, without having to make any manual volume adjustments. The wet level can be adjusted internally by a trimpot.

Always use a high quality regulated and isolated power supply for best operation. Daisy chain power cables may induce clock noise.

RAD DISTORTION

This is the classic ratty sounding distortion from the '80 and '90s, with some Dazatronyx tweaks.

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' metallic 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.
• NOS germanium transistors.
• NOS Telefunken black glass matched silicon clipping diodes.
• NOS Germanium clipping diodes.
• Nichicon film capacitors.
• Panasonic electrolytic capacitors.
• Dale Industrial grade precision metal film resistors (1%, 100 PPM / C).
• 600V Teflon wiring.
• Long life original CIC brand footswitch, Switchcraft audio sockets, Hammond enclosure. Usual stuff.

PROFESSIONAL DRIVE

This is the result of my work developing the classic TS overdrive circuit over many years, and critically evaluating every tone-shaping aspect of the signal path.

I've added a three-way switch which toggles between three modes, which is helpful to suit a broader range of pickups and play styles.

• SYM - Symmetrical clipping like the classic 808 overdrive, with a focus on mids.
  
• 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 chord detail to better shine through.
  
• FAT - Also asymmetrical clipping, but with a full bottom-end output.

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

This circuit was made using the following special components:

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

PLUS SIZE

The same as the compact unit - only with larger components, top-mounted sockets, and FET clipping instead of diode clipping. This is the result of my work developing the classic TS overdrive circuit over many years, and critically evaluating every tone-shaping aspect of the signal path.

I've added a three-way switch which toggles between three modes, which is helpful to suit a broader range of pickups and play styles.

• SYM - Symmetrical clipping like the classic 808 overdrive.
  
• 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 big bottom-end output.

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

I also offer an option for large, 2W metal film resistors.

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. There is automatic perceived volume compensation for the full sweep of the controls.

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.

As with all of my tremolo models, you should expected perceived unity volume with all depth and rate settings, without having to make any manual volume adjustments. The wet level is adjustable internally by a trimpot.

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.

CLASS A

Germanium amplifier

This is my best attempt at a classic 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 - particularly transistors. Photos should be used only as a general guide for construction and components quality.

N.B. for purity of design, this pedal uses a positively grounded case. As such, it needs to be run from an isolated power supply, or battery. Batteries are not preferred. IE this pedal may not be suitable for a daisy-chain power supply.

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 can dial in a fat bottom end to fake a big am. Lowering the drive thins this out if you want to push your preamp with the pedal. 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 origins of this circuit date back to the '70s. This framework became the basis of many boutique distortions during the boom of DIY pedals - probably due to its elegantly simple design, and rich effect.

The three-position switch toggles between amp models of varying bottom-end saturation and overall gain.

GERMANIUM FUZZ 2021

SOLD

This was a limited edition, special build. I only built two this year, to keep the project viable for me.

This is an old-recipe '60s germanium Fuzz Face. The transistors in this seconds unit are General Electric 2N43, and 2N123, where the manufacture date is the 13th week of 1956, and 4th week of 1958, respectively. These are some of the very early semiconductors which used a point-contact style junction.

Both units are now sold.
