Diamond Pedals Phase: All-Analog JFET Phaser Pedal (2/4/6-Stage)

Unmistakable Analog Character

The Diamond Pedals Phase is a highly anticipated modern revival of the original Diamond PSH-1 Phase, first introduced in 2008. Faithfully re-engineered to preserve its unmistakable analog soul, this next-generation pedal meets the demanding needs of today's space-conscious pedalboards without sacrificing an ounce of tone.

At its core, the Diamond Phase remains true to its legendary predecessor. It features a fully analog audio path built around six carefully selected and hand-matched JFET transistors in every single pedal. This meticulous approach delivers exceptionally smooth, musical phase shifting with a depth, warmth, and clarity that never feels artificial or over-processed.

Selectable 2, 4, or 6-Stage Architecture

From barely-there movement to deep, colorful modulation, the Diamond Phase captures the full history of phasing. A selectable stage toggle gives you three distinct phaser voices in a single compact enclosure:

• 2-Stage Mode: Offers light modulation and subtle movement. Perfect for gentle motion, tone enhancement, and always-on textures that add "feel" to your playing without overpowering your core tone.
• 4-Stage Mode: Delivers the classic, traditional phasing heard on countless iconic recordings. This highly requested, perfectly balanced sweep is a brand-new sound previously unavailable in the original Diamond phaser.
• 6-Stage Mode: Provides a throatier, more colorful response. Expect deeper notches, increased harmonic complexity, and bold, expressive psychedelic swirls.

Classic JFET Phaser Technology

The Diamond Phase utilizes a classic JFET-based phaser topology, where each stage acts as a voltage-controlled variable resistor. As the modulation signal changes, these JFETs shift the phase of the audio signal in a perfectly continuous sweep. Because Diamond carefully matches every JFET, the phase response remains incredibly even across all modes, avoiding the abrupt transitions or uneven swooshes common in lesser phasers.

Made For Today's Pedalboards

We cut the size, not the tone. Housed in an enclosure approximately half the size of the original PSH-1, the new Diamond Phase easily fits into contemporary setups. It features modern top-mounted jacks, soft-touch relay true bypass switching, and an incredibly smart power design. Running on standard 9-15VDC, it includes an internal voltage pump that boosts the circuit to a pristine 15V, ensuring massive headroom and clean, consistent performance with no fancy proprietary power supplies required.
