1. True Strobe Display Pattern in the ring of LEDs rotates left if the note is flat, and
rotates right if the note is sharp.
2. Sharp/Flat LEDs These activate if the note is more than 50 cents out of tune. These
are only active in "open tuning" mode.
3. LED Note Display Displays the note name in chromatic mode, or the string number
in open tuning mode.
≠ ≠
4. A4 440 Illuminates when the A reference is set to any value other than 440.0 Hz.
The range of A4 is 300.0 to 599.9 Hz in .1 Hz increments.
5. Drop Tuning Indicator You may drop the tuning up to 6 semitones.
6. Mode Indicator Six modes total. All except CHRM (chromatic) are fully
programmable. They may be set as an open tuning or chromatic, and each note may be
offset ±50.0 cents in .1 cent increments.
7. True Bypass, Muted Output
8. Mode/Calibrate Button Changes mode in normal operation. Hold down during
power on to change the A4 reference.
9. Mode/Drop Tuning Button Changes mode in normal operation. Hold down during

4. Play a note and observe the pattern in the LEDs. The direction of rotation indicates
whether the note is sharp or flat. The farther out of tune, the faster the pattern will
