Diamond Pedals has reissued its 2008 PHS-1 6-Stage JFET Phase-Shifter in a compact edition called the Diamond Phase, announced on April 16, 20261. The new phaser pedal keeps the original's analog JFET design in a smaller enclosure12.
The pedal offers selectable 2-, 4- and 6-stage phasing: 2-stage for light modulation, 4-stage for traditional phasing and 6-stage for what the report describes as throatier, more colorful phasing1. A mini toggle switch in the center of the pedal selects the modes2. The circuit is fully analog and based on six matched JFET transistors2.
Controls are Level (output level), Speed (sweep rate from 0.1 Hz to 10 Hz), Regen (feedback in the phase circuit) and Depth (intensity of the effect)1. The ON|DBL footswitch handles bypass and a double speed function, in momentary or latching mode, and the status LED is red for active and green for doubler mode1. There is an internal trimpot for JFET-bias fine tuning, top-mounted jacks and soft touch relay switching1. The pedal is hand-made in Montreal, Canada, and runs on a 9-15V DC PSU with roughly 80 mA current draw1.
The original version had a Phaser/Vibrato switch, which the report says "has been felt surplus to requirements on this occasion"1.
"The Diamond Phase goes for $249 / €279 / £249, and should be available widely at leading International Dealers as soon as this article goes live."
The US list price is $2491. Gearnews reports the pedal as available now2.
