Question Does the PolyTune Mini work with a bass Answer Yes, to a degree - the PolyTune MIni / Noir does not have the Bass mode that the original PolyTune and the PolyTune 2 have, so it'll only work in chromatic tuning, one string at a time. Because of this, getting the PolyTune/PolyTune 2 is a better idea if you want to use the polyphonic tuning mode with an active or passive bass.
