REVERB PROGRAMS
Spring - The Spring program emulates an excited spring reverb commonly found in tube amps with loads
of bouncy drip. Easily go from subtle to full-on surf rock and beyond. Experiment with the decay knob to
get more than normal amounts of reverb not found in traditional amp spring reverb tanks.
X knob adds a gentle, warm overdrive to the reverb input simulating overdriving the spring tank.
Hall - The Hall program provides the acoustics of large live sound spaces like concert halls to arenas.
Longer decays and higher X knob settings result in a massive wash of ambiance. Shorter decay and lower
X settings allow for a more intimate reverb expression.
X knob controls the size of the room; smaller at lower settings to larger room sizes as you increase X.
Plate – The Plate program emulates a smooth analog plate reverb with nice even diffusion inspired by
famous plates like the EMT 140.
X knob adds in gentle warm grit to the front end of the program simulating driving a hot signal into
the plate.
BFR - BFR is a no holds barred, big, f______, reverb. This is more than a giant arena reverb. It’s a hall-esque
reverb with rich and lush decay in a vast cavern filled with choirs of angels.
X knob controls the amount of diffusion applied to the delay network. At lower settings, the
delay taps are more apparent. At higher settings, they are smoothed out to create a soft bed of
reverb.
Rfrct (Refract) - The RFRCT program allows for lovely, charming, and glitch-like textures hovering over a
largely diffused reverb. The Rate controls on RFRCT change how often the glitch effects occur while Depth
controls the overall volume of the glitch effect.
X knob changes the feel of the glitching form dark and lo-fi at minimum, to bright and present at
higher settings.
Air - The Air program offers a larger diffused reverb with a subtle shimmer but has a more “crisp” clarity to
its decay. Explore slow-building sounds that don’t get in the way of your playing. Air complements keys
and synths as well.
X knob controls the amount of the wind and shimmer elements in the Air program. At zero, the effect
will be off. Turning clockwise will increase the volume of the air effect.
