Guitar World Verdict

The Pulse Doppler has a spacious sound in mono, but if you have a rig to handle it, you can send wet and dry signals to two separate destinations for a wider sound by using both rear-panel output sockets. Either way, it’s a massively versatile pedal that demands exploration.

Adrian Thorpe’s latest venture is an analogue phase-shifting pedal, designed in conjunction with Dan Coggins, formerly of Lovetone and Dinosaural. Dan was behind Lovetone’s much sought-after Doppelganger phaser/vibrato from the 1990s, which surely donated some of its DNA to this new project. 

The pair’s idea was to create a dream phaser pedal to deliver some of the effects heard on classic records, but also take things further still. The Pulse Doppler is based around a four-stage, two-notch phaser design, but comes with a set of controls for an extended range of sounds with variations on phasing, vibrato and tremolo.
