K. ETUNERLED—When the Tuner function is selected
the LED flashes faster as the guitar note moves away
in pitch (+ or -) from E. When in tune with E, the
yellow E Tuner LED and the green Tempo LED will
both illuminate solid.

solid. To assist in tuning, an E reference tone is

which plays repeatedly until the Start/Stop button
is pressed once again. The MIDI IN position turns
off the internal loop sequencer and allows external
loops to be played via the MIDI input.
