Dazatronyx - Melbourne, Australia

 

Philosophy

I began to design pedals in my late years of secondary school, and have remained dedicated ever since. Pedals provide me with a perfect balance of mental stimulation mixed with hand craft. It is my belief that life can be understood as an expression of rhythm and pattern. Building pleasant sounding effect circuits is my way of playing back with the universe. My design style might be thought of as a hybrid combination of vintage and modern technologies. I build each pedal myself, by hand, as I would for myself or a close friend.

All of the circuits are carefully hand soldered in my home to have a long lifespan, and be practical to service. The enclosures are drilled and powder coated in my garage. My name is Darron Thornbury, and I live in the outer south-eastern suburbs of Melbourne, Australia.

 

parts quality

All pedals have a 10 year warranty.

Here are some of the high quality parts which I commonly use in most of my pedal designs:

  • In-house durable powder coating (powders by Dulux Australia).
  • In-house durable printing.
  • 600V teflon insulated, silver plated, multi-strand copper wiring.
  • Reliable, long-life true bypass original CIC brand footswitch.
  • Lead-free soldering.
  • Hammond 1590 series aluminium alloy enclosures.
  • Copper > nickel > gold plated circuit boards.
  • Switchcraft audio sockets.

  OPTICAL TREMOLO

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.

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'.

Dazatronyx Rad Distortion

Dazatronyx Rad Distortion guts

 

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.

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

 

Temporarily sold out while printing more enclosures. Contact me for ETA / progress.

Revisions: 2021 Adapted to a Hammond 1590BS enclosure to include top-mounted connections. Large 10mm bezeled LED was replaced for a clear lens. Internal DIP switch mods removed. Parts selections revised.

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.

OPTICAL TREMOLO

My Optical Tremolo project was my first attempt at a completely unique and original circuit design, starting while still in high-school. It ended up taking ten years of tinkering before I was completely satisfied with it. I continued developing the same circuit and five years later finished the Stereo Panning version. This has taken many years, and 9 proto designs. This is an all-analog circuit for both the signal and the oscillator.

The function of a 'harmonic' tremolo, as opposed to a regular tremolo, is normally described as splitting the audio spectrum into two registers of treble and bass, and then modulating the volume of each register in opposing directions. IE at one side of the wave you hear the treble, and at the other side you hear the bass.

This particular circuit works a little differently, in that instead of modulating the volume of two registers, it actually modulates the frequency cut of each register. This is done using two very particular photocell sensors, paired against lights which fade in and out.

As with all of my tremolo models, you should expect 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. There is an internal voltage boost for increased headroom, while keeping low noise levels.

The waveforms are modified from my standard tremolo to be symmetrically shaped for a rounder "vibe" sound.

BIG FUZZ - PLUS SIZE

 

Limited Edition

Comings soon. Waiting on a demo video to announce launch date. This is a larger sized build of the compact model. A keen eye will notice some additional components, as well as some component substitutions such as polystyrene 'smoothing' caps and FET clipping instead of diodes.

The polished finish turned out not to be a sustainable technique. As such, this will be a limited batch of 10x polished units in this aesthetic.

Comes with a custom serial numbered cotton bag.

Price will be AUD$269 within Australia, and a little extra overseas.

Dazatronyx Stereo Panning Optical Tremolo   STEREO PANNING

 OPTICAL TREMOLO


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.

Dazatronyx BSIAB2   BSIAB2

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.

For demos on how this pedal sounds, check out the Lovepedal Les Lius as it will sound like that circuit when the gain boost switch is engaged.
