Does a PolyTune Clip work with a baritone guitar tuned in B?
Yes, the PolyTune Clip will work fine with a baritone guitar tuned to B as this is standard tuning tuned down 5 semitones. Thus in order to tune your baritone guitar using PolyMode, you will have to select the B tuning mode on the PolyTune Clip. Just press the Tuning Mode Button to cycle through the available tuning modes and select B.
Of course, you will still have the choice for chromatic tuning, one string at a time.
For further information please see the PolyTune Clip user manual on page 9.
