My tremolos are easily my favourite circuits, and have occupied more of my design time than anything else. This was my first effect design from scratch, which I started in high school. Development took over a decade before I was happy with it.

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. I feel 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.

I prefer to use the asymmetrical mode for the square wave, as the signal stays 'on' longer, with less gap time.

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 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.
