Footswitch
The footswitch, when plugged in, works simultaneously with the front panel. Since it doesn't have
in common the LED rings that the front panel has, the footswitch must do some transforming of its
own. Refer to the diagrams below to see which LEDs and switches play a role in tuner use.
To access the tuner function from the footswitch, press both the EFFECTS SELECT MODE button
and the BANK SELECT MODE button simultaneously. The footswitch indicates that it is in Tuner
Mode by dimly illuminating all four yellow bank LEDs. In the diagram below, the letters listed above
the footswitch LEDs correspond to the six-strings of a six string guitar tuned to a standard tuning.
Unlike the front panel, the footswitch is labeled E, A, D, G, B and E (top left to right) to aid in quick,
remote tuning. These labels designate the note represented by the green LED below it. Upon
striking a note, a green LED will illuminate just as the LED ring did in the front panel description.
Though the green LEDs function in both guitar and chromatic tuning modes, they will respond
differently. See the following section for a description of the two tuning modes.
Master Footswitch Tuner Indicators/Controls:
being tracked. In chromatic mode, if the current note is not E,A,D,G or B
E
Secondary Tuner Indicators:
counter clockwise = flat
clockwise = sharp
These two rows of LEDs form a single LED ring like those found on the front panel.
The note LEDs (EADGBE) found in the Master Footswitch diagram above
depict the note that the LED ring is currently tracking (see dashed line).
