• OUTPUT (red LED): Sets the overall output volume of the effect
which is useful for matching the level of the effect vs. the bypass
volume. It can also be used to prevent clipping if longer reverb
times are used with continuous loud inputs.
• DIFFUSE (green LED): Adjusts the amount of “spreading” in the
feedback loop. The higher this parameter is set, the more the
sound will be diffused as it circulates in the reverb loop. Sharp
transients (like guitar pick noise) will be smeared out over time.
At least a small amount of diffusion is recommended to create
natural sounding reverbs. Larger amounts can smooth over
what might otherwise be an undesirable set of individual early
echoes. However, maximum diffusion may produce some ring-
ing at certain frequencies.
• RATE (red LED): Adjusts the rate of the LFO (Low Frequency
Oscillator) that is applied to the reverb. The modulation is an
optional setting that adds some nice animation to the reverb
sound. In the physical world, reverb modulation would be the
sound created in a room with moving walls. Obviously, real
rooms don’t have moving walls, but they do have moving air cur-
rents, and also a complexity of reverberation paths way beyond
what we can simulate. With a slow rate and low depth setting
the LFO provides an added level of realism to our reverb.
• BASS (green LED): Like the TREBLE control, the BASS param-
eter works like a bass tone control by damping the amount of
bass frequencies that go through the feedback loop. Set to full
counter-clockwise, this is most bass damping which will tend
to cut the overall bass tone. Full clockwise will allow the bass
frequencies to ring out resulting in more overall bass.
