Dazatronyx Optical Tremolo

The first Dazatronyx circuit! Owner Darron Thornbury confesses that tremolos are easily his favourite circuits to design and build, and you can certainly tell a lot of time and energy has gone into its design as this pedal is wonderfully musical tremolo that just sounds phenomenal. 

Dazatronyx pedals are all hand-built by Darron right here in Melbourne, Australia. 

How does an Optical Tremolo work?

By shining a fading light against a photo-sensitive field, this tremolo uses all-analog photo-coupling to restrict and fluctuate the output volume. Careful waveform construction, with non-linear photocell coupling, creates an organic and lively volume fluctuation, far divorced from sounding like a basic electronic waveform function. The square wave is similarly processed, so as not to sound like a computer.

Symmetry switch:

This toggles between two modes which are subtly different. The asymmetric mode (up) has a slightly uneven rhythmic pattern. This mode is sweeter, as it has a less obvious tempo. The modulation ascent and decent waveforms have slightly different shapes, which change and adapt for volume with different speeds and depths. This can be heard with emphasis in the original liquid spinning can tremolos.

The symmetrical mode (down) has an even 360 degree spin, with a very slightly deeper scoop. It has a classically pronounced tremolo shape.

This circuit operates with in a split rail power supply for increased headroom, and has a very low noise level.

As with all of Dazatronyx 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.
