Electro Harmonix Nano Pulsar Stereo Tremolo

From the manufacturer:

The Nano Pulsar takes tremolo beyond the ordinary and mundane. Equipped with a collection of tremolo-modulating waveforms and the option of operating in Triangle or Square Wave modes, the Nano Pulsar is a tremolo/panner treasure chest. In mono, it's simply amazing, or, connect it in stereo to create shifting waves of sound that surround you and fill your space with weaving, pulsating energy.

For all its power, the Nano Pulsar's layout is intuitive and using it is easy. There's often a perceived volume drop with tremolo when the effect is engaged so we've included a Volume control. It allows a player to fine-tune their output level when the effect is on, and is a very useful addition.

Unlock a world of advanced sound shaping and control. The compact Nano Pulsar will be your do-it-all, go to pedal for all things tremolo and panning.
