This Rotosound RKH1 The King Henry Phaser pedal was hand built at the Rotosound factory in Sevenoaks, Kent. Following on from the massive success of the reissue of the Rotosound Vintage Fuzz Pedal, Rotosound announced the launch of a collection of six new and original retro guitar effects pedals.

The Wobbler tremolo, the King Henry phaser, the Pusher compressor, the Crusader chorus, plus the Aftermath analogue delay and Leveller EQ pedals.

All have been designed in conjunction with John Oram of VOX and Trident fame. John has spent nearly half a century developing innovative electronic musical equipment and has been responsible for a number landmark custom-designed products.

Using John’s considerable knowhow, and Rotosound’s attention to detail, all the pedals are built to deliver studio grade performances, are intuitive to use and have impressive capabilities. The pedals incorporate today’s technology for consistency and sustainability combined with real 1960’s design for style and tone.

They are hand wired in the UK using authentic components. Each pedal is finished in a durable pressed steel box in a distinctive range of eye-catching coloured hammer powder coatings.

The King Henry Phaser pedal makes it easier to sweep through the entire audio range from shimmery to vibrant. This comes with PEAK, a control for the wider ranging of phase effects.

For a truly vintage tone from one of the best British vintage manufacturers in the industry, The King Henry Phaser produces a thick, luscious tone which takes you right back to the 60s and 70s.
As you tweak the settings, you quickly arrive at some really cool and interesting tonal destinations – from psychadelic rock to funk auto-wah.

This pedal is in absolutely mint condition and comes with its original box and paperwork (the box is a little tatty in places).
