Legendary spring reverb returns in compact Eurorack format with the Behringer SPRING REVERBERATION 646, bringing that unmistakable twang and spatial dimension to your music. This faithful recreation of the iconic Grampian Type 636 puts the same secret weapon used by Pete Townshend and reggae dub pioneer Lee “Scratch” Perry right into your modular setup.
The 646 takes a refreshingly straightforward approach – no digital emulation or unnecessary complexity here. At its heart are dual mechanical springs that generate the lush, dynamic reverb character that simply can’t be replicated by other reverb types. The authentic spring mechanism even produces that classic “sproing” sound when given a gentle bump, though we recommend treating it with care.
This compact unit gives you direct access to the same legendary tone that shaped countless classic recordings. Now you can add this essential vintage character to your own productions, creating everything from subtle spatial enhancement to dramatic dub-style effects with genuine mechanical spring reverb.
