Synthetic Sound Labs‘ Doug Slocum let us know that their SSL 2530 Tube VCA / Timbral Gate, a module based on 1950’s era Soviet vacuum tube technology, is now available in Eurorack format. It was introduced in MU format at the end of 2020.
The module can be used for a variety of purposes, ranging from VCA tasks to adding analog warmth to extreme distortion effects and more.
Slocum describes the module as “a wild blend of vacuum tube warmth and distortion, along with an incredibly useful VCA that is so much more than the sum of its parts”.
The module uses miniature pencil-sized vacuum tubes that were developed and refined by the Russians 60+ years ago. They are low-current and low-voltage devices, so they don’t require the high-voltage power supplies that are required for most other vacuum tubes.
The module is designed in conjunction with Ken Stone (CGS), creator of a wide range of DIY projects for synthesists. SSL has expanded on Ken’s design, adding LEDs behind the tube, to visually emulate the glow of the filament, and pulsating blue LEDs that simulate tubes as they are being driven by control voltages.
