Electro-Harmonix Pulsar Variable Speed Tremolo vs Zvex Tremolo Probe
The Electro-Harmonix Pulsar Variable Speed Tremolo and the Zvex Tremolo Probe are both pedals. The Electro-Harmonix Pulsar Variable Speed Tremolo leans smooth and spring.

Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement. Shown only within a gear class, and only where there's enough evidence to be meaningful.41% — somewhat different

The Electro-Harmonix Pulsar is a variable-speed tremolo pedal from Electro-Harmonix, delivering optical-style amplitude modulation tremolo with Rate, Depth, and Shape controls. The Shape control selects between different tremolo waveforms from smooth sine wave to sharp square wave chopping. The Pulsar provides studio-quality tremolo with a wide Rate range from gentle slow pulse through fast, machine-gun tremolo chop.
The Zvex Tremolo Probe is a theremin-controlled tremolo pedal from Z.Vex Effects (Minneapolis, Minnesota), using a proximity antenna (theremin-style) to control tremolo speed — the closer a foot or hand moves to the antenna, the faster the tremolo oscillates. Like the Wah Probe and Fuzz Probe in the Z.Vex probe family, it eliminates conventional depth/rate knobs in favor of gestural, proximity-based speed control for expressive, hands-free tremolo variation.
