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.
