The Damp Reverb (NRV-3) packs three reverb algorithms into a compact pedal. Plate is modelled on the EMT 140 studio plate, spring recreates a spring tank for a bouncy, bottom-heavy surf and rockabilly character, and hall is based on the Lexicon 224 with a warm, lush decay. The types are changed by tapping the footswitch, and the Decay, Level and Tone controls are simplified for quick setting.

Holding the footswitch gives access to secondary functions, Shimmer and Freeze. Bypass can be set to true bypass or buffered bypass with trails: hold the footswitch while powering up (without USB connected) and the footswitch LED shows the mode, green for buffer and red for true bypass. The dry signal stays analog for low noise and no added latency, while the reverb runs through 48 kHz DSP.

The pedal supports stereo input and output using 1/4" TRS plugs with stereo mode selected. It runs from a 9V DC negative-tip supply and draws under 100 mA. Firmware version 2.0 is available for macOS and Windows, and manuals are offered in English, French, Italian and Japanese.
