Electro-Harmonix Stereo Pulsar
Electro-Harmonix · pedal
The Electro-Harmonix Stereo Pulsar is a variable-shape analog tremolo pedal with two independent stereo outputs. Controls include Rate, Depth, and Shape plus a three-position waveform switch covering sine, sawtooth, and square wave modulation. The Shape knob morphs continuously between waveform types within each mode, producing everything from gentle, rounded amplitude swells to hard gated staccato chops. Stereo outputs enable true ping-pong panning between two amplifiers. Discontinued in 2025.
