Branching out after the success of last year's fuzz pedal reissue, Rotosound has teamed up with electronics guru John Oram for a new range of effects, including this pedal: the King Henry Phaser.

"The King Henry offers lots of variation on that 70s phaser sound"

Phasers might not be the most popular modulation pedals these days, but they were a big deal in the early 70s, before chorus and flangers. The King Henry offers lots of variation on that 70s sound, via rate and depth controls.

Its secret weapon is the peak knob, which brings regeneration into the mix and emphasises the 'wow' in the sweep, giving you a sound like an auto-wah when you turn up the depth.

Trevor Curwen has played guitar for several decades – he's also mimed it on the UK's Top of the Pops. Much of his working life, though, has been spent behind the mixing desk, during which time he has built up a solid collection of the guitars, amps and pedals needed to cover just about any studio session. He writes pedal reviews for Guitarist and has contributed to Total Guitar, MusicRadar and Future Music among others.
