Moon Pool Tremvelope Phaser £165

Harking back to the first Pigtronix pedal, the Envelope Phaser, the Moon Pool is an analogue phase shifter and tremolo that can manipulate the effect via your playing dynamics. A three-way toggle switch allows you to use the two effects individually or combined. Each effect has a Speed control, but Depth is set globally via a single knob, and each also has its own three-way switch to set how it responds to dynamics – either no response or an increase or decrease of speed with harder playing, another knob setting the overall sensitivity.

We preferred the bias tremolo’s rounded throbby pulse to the phaser’s more workmanlike nature, but their combined texture yields a range of ethereal modulations, some with rhythms that play off each other. Plus, the envelope action will give you an expressive layer to exploit for even more unusual effects.

VERDICT A pedal that helps you explore the possibilities of mixing phasing and tremolo
