Nano Pulsar

The Nano Pulsar is an analog tremolo and auto-panner with a Shape knob that morphs the modulating waveform. A switch selects between a triangle-based mode (rising sawtooth through triangle to falling sawtooth) and a square-based mode (narrow pulse through square to wide pulse). Rate covers roughly 20 seconds per cycle up to 30 Hz, so it can move from slow swells into ring-modulation-like sounds when Rate and Depth are pushed high.

Depth sets the amount of tremolo, with the widest dynamic range and widest stereo field at about the 1 o'clock position. Turned further, the modulation becomes asymmetric and swings the signal between positive and negative phase, giving a warped, synth-like tremolo. A Volume control can add up to 12 dB of boost to offset the level drop that tremolo often causes.

There is one input and two outputs (Mono/Left and Right). The Right output carries the same effect with the waveform shapes reversed, which makes stereo panning possible with two amplifiers. A footswitch toggles buffered bypass, and the status LED pulses at the modulation rate. Power comes from the included 9V battery or an optional center-negative 9V supply.
