Vermona DSR-3

Vermona’s DSR-3 is a powerful spring reverb that provides stereo processing and additional operating modes that facilitate parallel and serial usage. The module features high quality AccuBell springs and a two-band EQ with dedicated bass and treble controls that have been customized to the frequency range of each spring. 

The unit features both TS and XLR ins and outs, complete with custom transformers for maximum sonic quality. This also enables the DSR-3 to be used as a DI-box. Additionally, the unit’s channels can be layered in various ways via three different operating modes, or used independently. In Stereo Mode, the DSR-3 processes stereo sources, with the first spring reverb channel governing the most important parameters. In Dual Mono Mode, the unit processes two independent signals, while Serial Mode reroutes the reverberated signal present at the first channel into the second channel.
