Italian pedal maker Foxgear has introduced the Multitune compact effect pedal, which the company touts as the only stompbox capable of tuning a guitar polyphonically in open tunings.
At the core of the Multitune is an AnalogDevices DSP, which Foxgear uses to run its note detection software, and a digital compressor that allows players to tune each note by gently striking the strings of the guitar only one at a time.
