Combines two different high quality studio reverbs (A and B) with independent controls for decay, size, pre-delay, and EQ. Control mix between the dual reverbs for rich, dense stereo reverberation, or use this effect to smoothly transition between two entirely different reverb sounds.

DualVerb Algorithm Controls
Mix [MIX]
wet/dry mixer, 100% is all wet signal
Reverb A Decay [A-DCY]
decay for reverb A in seconds or note-based in Tempo Mode
Size [SIZE]
adjusts the size of both reverbs A and B to give many different size combos with one knob
Reverb A PreDelay [A-PDLY]
pre-delay for reverb A in milliseconds or note-based in Tempo Mode
Reverb A Tone Control [A-TONE]
Tone control for reverb A
Reverb B Tone Control [B-TONE]
Tone for reverb B
Reverb B Decay [B-DCY]
decay for reverb B in seconds or note-based in Tempo Mode
Reverb B PreDelay [B-PDLY]
pre-delay for reverb B in milliseconds or note-based in Tempo Mode
Reverb A/Reverb B Mix [VRBMIX]
mixer for A and B reverbs, in stereo this mixes stereo channels, set at extreme results in dual mono reverbs (A on left, B on right)
Resonance [RESNCE]
Resonance mixer for A and B Tone controls. Affects the sound unless [A-TONE] and [B-TONE] are both set to 0.
Output Level
At 0 the output level is unaffected. Increase the output level of the effect by up to 20 dB or lower by 30 dB.
Tempo is turned ON/OFF on the H9 by simultaneously pressing the Right Footswitch and the PRESETS button. With Tempo OFF, tapping can be used to adjust delay parameter values (displayed as milliseconds or Hz). With Tempo ON, tempo is in BPM.
Turn effect on or off..
The Middle Footswitch can be programmed to act on the loaded Preset as a programmable controller allowing the user to switch between the normal Preset parameter values and a programmed, alternate set of parameter values. It’s like having two Presets in one.
If Tempo is ON, the display indicates the current tempo in BPM (30 to 500 BPM) while tapping and the Tap LED will blink at the BPM rate. If Tempo is OFF, the display indicates the parameter value (milliseconds for most algorithms).
