Image placeholder title

Prophecysound Systems has introduced its Pi­-Phase mk2 phase shifter, a compact and all­-analog reproduction of the original Seventies classic Mu-­Tron Bi-­Phase.

From the company's press release:

Suitable for guitar, bass, keyboards or outboard studio processing, the Pi­-Phase mk2 phase shifter is built entirely in Adelaide, South Australia, utilizing “best of breed” manufacturers and suppliers, along with decades of in-­house expertise.

Compact in size (50mm H x 188mm W x 122mm D), the Pi­-Phase mk2 makes authentic phase sounds available to the working musician or producer, with a warm liquid tone that is instantly recognizable from a range of classic recordings.

● Two independently­ switchable phase sections, two LFOs, and a flexible architecture that allows serial (mono) or parallel (stereo) operation
● Support for external expression or CV control of LFO rate or wah-­like phase sweep
● True-­bypass operation + LED indicators for each channel
● A compact and robust powder­-coated enclosure and industrial-­strength polycarbonate labels for looks that will resist the worst live gigs have to offer
● External AC 15-volt adapter (not supplied) operation, enabling retention of the internal high-­headroom design of the original
● Includes miniature reproductions of the original unit’s program cards and blank program cards for recording of user settings

“We believe the Pi­-Phase mk2 is as close a reproduction of the original Mu-­Tron Bi­-Phase it’s possible to build,” said Mike Both, Prophecysound Systems designer/director. “While we employ modern surface-­mount technology for most of the pedal, the all important LED/opto­-coupler section of the design utilizes ‘old-­school’ through­-hole components. The result is a wonderfully rich and warm sound outside of the capabilities of software and plug­ins, at a price­ point that allows musicians to finally have ‘that’ sound on their pedal boards.”

The all­-important final stages of assembly of the Pi­-Phase mk2 are done by hand, and final calibration is performed according to the original technical specifications.

The Pi­-Phase mk2 is available for AUD599 (+ 10% GST within Australia)—about $472 U.S.—and is sold worldwide directly through the Prophecysound Systems site ​and through authorized Prophecysound Systems dealers. For an up-­to­-date list of international dealers, please visit p​​
