tremolo by lamplight

A real lamp, pulsing in the panel. LAMP is the tremolo in old guitar amps made into a module: an analog LFO heats a filament behind a window, a photocell reads it, and the light opens the volume and the tone together. The filament heats faster than it cools, so it throbs rather than chops, and patching an envelope into LIGHT turns the bulb into a slow low-pass gate. A digital spring tank sits after it, and FLICKER sends the light out as a CV.
