Shows the parameters and the values.
2 [RATE] knob
Adjusts the speed at which the eect sound changes.
Each time you press the button, the rate indication
switches.
Frequency #Tempo (BPM)
Example indications
0.01 Hz = “0.01”, 1 Hz = “1.00”, 10 Hz = “10.0”,
tempo: 120 = “120.”, tempo: 1000 = “1.0K.”,
tempo: 10000 = “10K.”
* When the mode is ROTARY, this switches the speaker’s rotation
speed between SLW (slow) and FST (fast).
3 [DEPTH] knob
Adjusts the depth to which the eect sound is
modulated.
* When the mode is ROTARY, this adjusts the amount of preamp
distortion. When the mode is SLICER, this adjusts the balance
between the eect sound and the direct sound.

stereo. (If you don't use stereo output, this will
not produce the intended eect.)
