Spice up the sounds with stereo output Connected as a mono pedal the Electro Harmonix Stereo Pulsar is exactly the same as the original Electro Harmonix Pulsar: a tremolo pedal that allows significant control over the shape of modulating waveform. However when you hook up the Stereo Pulsar in stereo you have a panner pedal that will send your instrument back and forth between two amps with the same control over waveform shape. This quite simply sounds incredible and is an effect everyone should try but the Stereo Pulsar makes it easy to access these lush panned tones.
