Footswitch
When the green light above the footswitch is on, the effect is active. Step on the
footswitch to bypass the AFX • Reverb. When the effect is bypassed, your in-
strument signal passes through an all-analog buffered signal path. This buffered
path provides an incredibly low-noise output useful for driving long cable runs,
such as to a mixing console.
