Tremble

Amp and pedal tremolo, from surf throb to choppy gating.

Pulses the volume or pans a part across the speakers, and keeps the level steady as Depth goes up. A lopsided Bias throb, a smooth Opto pulse or a shimmering Harmonic one.

Tremble in brief

What it is
A free tremolo and auto-pan for guitar, keys, pads and bass.
What it does
Locks the pulse to the bar or runs it free, and shapes it from a smooth sine to a hard square.
What it sounds like
A guitar that throbs in place, keys that move from speaker to speaker, or a slow, swelling pulse on a pad.

How it is built

Bias, Opto and Harmonic circuits each pulse in their own way. Harmonic splits the sound into bands and moves the balance between them, so it changes tone as well as level. Mono, Stereo and Pan modes decide where the pulse sits. Character adds the circuit's imperfections, and at zero the effect is a clean, exact change in level. Level is compensated automatically as Depth rises, with a Volume trim after.

Shape and Symmetry are different

Shape sets the curve of each pulse, from a smooth swell to a hard chop. Symmetry sets how long the loud part lasts against the quiet part, with even at the centre. Together they make the same chord answer the groove in different ways.
