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.

CLASS A

Germanium amplifier

My germanium boost pedal. Voicing switch:

• Mid: Effective at boosting for more drive, without the bottom end getting too flabby.
• Bright: Slightly fuller than a classic treble booster.
• Full Cream: Extra body, and fat tone.

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. IE this pedal may not be suitable for a daisy-chain power supply. Batteries are not necessarily preferred.

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.

A Mullard OC44 option is available in limited availabilty. These are sent with a custom case and cotton bag.

Revisions: In 2020, the circuit was flipped to a positive-ground arrangement, due to increased availability of isolated power supplies. At that same time, small changes were made to further reduce germanium background noise, and to improve the smoothness of the clipping and compression. The early circuit had many variations, being my first production pedal. This build has changed enough to label this as circuit 'V2'.

BIG FUZZ

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 modifications have been made to improve the tone and playability of the pedal.

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 differing amount of mid-scoop. This is a famous love-hate element of the circuit. Having a variable mids tone knob is incredibly helpful.

This effect is not fussy about input signal impedance, signal chain position, or operating temperature.

This is a small form factor box - the same size footprint as a small MXR pedal.

Returning very soon. Contact me for reservations or inquiries.

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. The 'stock' silicon mode is the classic ratty sounding fuzz-distortion from the '80s and '90s. This is achieved by a two-stage distortion of first overdriving the 308 amplifier chip into fuzz, and then recovering some shape by further compressing the signal using hard-clipping silicon diodes.

In the germanium mode, the silicon chip fuzz has been removed. Germanium transistors and germanium diodes are used to achieve a rounded and organic overdrive-distortion.

An internal trimpot can dial the mid/high drive saturation. Turning this completely to the right achieves the classic metallic ratty distortion. Turning this left achieves a flattened response.

A small version is also available with top-mounted jacks. Contact me for that.

PROFESSIONAL DRIVE

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

The 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.

After a decade of development, I've created this completely unique circuit as my ideal tremolo. This is easily my favourite effect circuit.

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 stereo channels. 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.

This circuit is optimised for a guitar signal level. A line level version is available on request.

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.

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 effect became the basis of many boutique distortions during the boom of DIY pedals - probably due to its elegantly simple design and rich tone.

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

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.
