News from the Labs

Dwyfor Tech Deuawd
15 Jun 2025 Dwyfor Tech
We are ecstatic to announce our first new module in almost a year and a half - Deuawd. The name means 'duet', and is testament to its two outputs and mono-to-stereo abilities. At its heart, it's a six-pole phaser and is capable of acting as such, but a few unique touches let it do a whole lot more. Take a look and see what it can add to your rack!
