Each of these toggle switch positions can be combined with the CIRCUIT Selector Knob for the utmost
tonal variety.
SWITCH Toggle Switch
The SWITCH Toggle Switch is a 2-way toggle switch that sets the footswitch action. BYPASS causes
the footswitch to act as a normal engage/bypass footswitch. MUTE will mute the outgoing signal
from the ZIO when the ZIO is bypassed. In MUTE mode, the secondary "TUNER/LINE" output will
remain unaffected so that you can use your tuner while the signal is muted.
ON/OFF Footswitch
Click the footswitch to engage or bypass the pedal. In BYPASS mode, the footswitch acts as a normal
engage/bypass footswitch, and you will still hear the bypassed signal when the ZIO is off. In MUTE
mode, switching the Zio OFF will mute the MAIN OUTPUT, killing the outgoing signal entirely.
