Mode Descriptions
I
Combination of standard Leslie 122 sound and natural overdrive.
This is the mode with the broadest range of uses.
II
Combination of Leslie 122 with on-mic setting and natural overdrive.
This produces a sound with an emphasized sense of tremolo.
III
This mode combines the sound of the Leslie 122 with the distortion of
a Marshall 1959.
This is a whole new sound, unavailable with any regular system, with
a particularly intense distortion.
IV
This sound combines the UNI-V, modeled on the “Uni Vibe” effect,
which recalls the late ’60s and the ’70s, together with the Marshall 1959.
The intensity of the UNI-V effect is adjusted with the BALANCE knob.
