We tried a few reverb circuits/methods and we always come back to our BerryVerb.
It is the only true Reverb pedal in the GUP Tech catalog. Built using the same FV-1 DSP chip as our Widow, the BerryVerb features 8 different modes, associated with their own controls (labeled P1-2-3).
The Mix knob allows for a 100% "wet" signal and the Reverb settings are adjusted with the "P1", "P2", and "P3" knobs.
The output signal can be boosted by up to 5 dB with the "volume" knob.
Power consumption: 63 mA
Voltage: 9 Vdc Center Negative
