Footswitch
Step on the footswitch to bypass the Aura effect. When you stomp, you'll hear
the dramatic difference between the Image blend and the dry pickup. When
the light above the footswitch is on, the Image is active. Note when the effect is
bypassed, your guitar signal remains buffered. Also, if the blend knob is set to
 o'clock, you will hear no difference between active and bypass states.
mute (optional mode)
You may set up the footswitch to alternate between the Image blend and muted
output. To enable the mute option, hold the footswitch down until the LED
flashes. Repeat to return to bypass.
