The lamp of the button lights up to indicate that Tremolo is on. Press the button
again to turn Tremolo off and Chorus on (the LED turns off).
1 Tremolo Speed
Determines the speed of the Tremolo (rapid rotation) effect.
Range: 4.75Hz – 7.77Hz
2 Chorus Mode
Determines the effect applied when Tremolo is switched off: a slow chorus
effect (SLOW) or STOP. Use the SLOW setting when you want to have a
constant rotating speaker sound.
3) Realtime control of Tremolo effect
Once the Tremolo effect has been turned on and set, you can control the effect
in real time from the panel or from the Left Footswitch (page 97). Simply press
the TREMOLO (FAST) button in the DISPLAY SELECT section to turn the
Tremolo effects on and off while you're playing. This button functions just like
the fast/slow switch on an actual rotating speaker cabinet. When Tremolo is on,
the rotation effect is fast; when off (Chorus), it is slow. The speed change is
gradual, effectively simulating the slowing down and speeding up of a rotating
speaker. You can also use the Left Footswitch to control the Tremolo effect in
the same way, if the Footswitch has been properly assigned.
