Finally, the Diamond Phase returns! From subtle to saturated this pedal is a sonic delight! 

The Diamond Phase is a modern revival of the original Diamond PSH-1 Phase first introduced in 2008—faithfully re-engineered to preserve its unmistakable analog character while meeting the needs of today’s pedalboards.

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

From barely-there movement to classic swirl and deep, colourful modulation, the Diamond Phase captures the full history of phasing—refined, compact, and unmistakably Diamond.

A selectable 2-, 4-, or 6-stage architecture gives you three distinct phaser voices in a single pedal:

• 2-Stage Mode offers light modulation and subtle movement, perfect for gentle motion, tone enhancement, and always-on textures that add feel without drawing attention.
• 4-Stage Mode delivers classic, traditional phasing—a sound not previously available in the Diamond phaser—with the familiar, balanced sweep heard on countless iconic recordings.
• 6-Stage Mode provides a throatier, more colorful response, with deeper notches and increased harmonic complexity for bold, expressive, and psychedelic sounds.

The Diamond Phase uses a classic JFET-based phaser topology, where each stage is built around a voltage-controlled JFET acting as a variable resistor. As the modulation signal changes, these JFETs shift the phase of the audio signal in a smooth, continuous way.
