This simulates the spring reverb that is built into guitar amps. Use the [REVERB]
knob to adjust the mix amount for the reverb sound. If you don’t want to use
reverb, turn the [REVERB] knob all the way to the left so that the mix amount is 0.

The VT15/30’s reverb operates independently of the other effects.

Pressing the [BYPASS] switch will not bypass the reverb.
