Operating the PolyTune 2
Polyphonic Tuning Mode
The PolyTune 2's signature feature allows you to tune all strings simultaneously. Simply strum all open strings on your guitar or bass, and the display will show the tuning status of each string. Red LEDs indicate flat notes, green LEDs indicate sharp notes, and a central green bar indicates a perfectly tuned string.

Chromatic (Monophonic) Tuning Mode
For precise individual string tuning, the PolyTune 2 automatically switches to chromatic mode when you pluck a single string. This mode provides a traditional needle-style display for highly accurate tuning.
Strobe Tuning Mode
The PolyTune 2 features an ultra-precise strobe tuning mode with +/- 0.1 cent accuracy. This mode is ideal for professional musicians and technicians who require the highest level of tuning precision. The strobe display provides a visual representation of pitch deviation, allowing for extremely fine adjustments.
true Bypass
The pedal incorporates true bypass circuitry, ensuring that your instrument's tone remains completely unaffected when the tuner is disengaged. This prevents any signal degradation or tone coloration.
Silent Tuning
When the PolyTune 2 is engaged, it mutes the output signal, allowing for silent tuning on stage or in the studio without disturbing your audience or recording.
