The letter name of the note is displayed, and vertical bars on either side of the longer vertical center bar will illuminate red to indicate varying degrees of sharpess (to the right) and flatness (to the left). Precise numerical pitch values (in cents) also appear on both sides of the display. When the note is in tune, the center vertical bar will illuminate in green. When finished tuning, exit tuner mode by pressing the PRESET LAYER button. Note that tuner use mutes speaker output. and that the GTX-7 Footswitch also has a tuning function (see page 44).

Note also that when in TUNER mode, the original Mustang GT “bouncing ball” tuner mode remains available by pressing the bottom LAYER BUTTON corresponding to “view” in the DISPLAY WINDOW (see illustrations below). Mustang GTX automatically saves the user’s preferred tuner mode.
