We've tried a couple of Reverb circuit/method and we always come back to our BerryVerb. It's the only true Reverb pedal in the GUP Tech catalogue. Made from the same FV-1 DSP chip as our Widow, the BerryVerb is loaded with 8 different modes, paired with their own controls (tagged as P1-2-3).
The Mix knob allows a 100% wet signal and the Reverb parameters are adjusted with the "P1", "P2" and "P3" knobs.
Output signal can be boosted up to 5 dB with the "volume" knob.
Power consumption : 63mA
