The Lovetone Doppelganger is a four-stage optical phaser first released in 1995, designed by Dan Coggins of Lovetone. It doubles as a vibrato, and MusicRadar has described it as "a much-feted phaser/vibrato from the 1990s, and a Coggins original"12. RockBoard lists it as a rare pedal3. Players known to have used it include The Edge, Johnny Marr, and Ed O'Brien, among others2.
The sound
GuitarPlayer's reviewer described the Doppelganger as having "a sound very similar to that of the classic Uni-Vibe"6. Because it is an optical phaser that also runs as a vibrato, it sits in the same territory as the vibe-style pedals players reach for when they want that swirling, rotating-speaker character. For more on that family of effects, see Vibrato Pedals.
Controls and features
JHS Pedals, in its history of Lovetone, notes the pedal's waveform control among its front-panel features5. Aion FX also points out a visual detail that sets the Doppelganger apart: each pair of phaser stages has its own rate/depth LED, so in every mode there is always a visual representation of how the signal is being modulated2.
The pedal also features expression pedal inputs, according to JHS Pedals, letting a player sweep the effect by foot5.
The 1999 update
The Doppelganger was updated in 1999 with three new features2:
- A Dry Out jack, allowing for stereo operation when combined with the pedal's other output
- A Square Wave toggle
- A Slow toggle
Aion FX reports that the Square and Slow features are backwards-compatible: with Square and Slow turned off, the pedal is identical to the V1 circuit2. Players hunting an original-style sound on a second-version unit can simply leave both switches off.
The ThorpyFX Pulse Doppler connection
The Doppelganger's circuit has a direct descendant. Guitar.com reviewed the ThorpyFX Pulse Doppler as "the Lovetone Doppelganger reimagined," the third in ThorpyFX's Lovetone MkII series, created with original Lovetone designer Dan Coggins and redesigned from the ground up4. It is a modern redesign rather than a copy of the original pedal.
