The Boss GP-10S Guitar Processor works in conjunction with a Roland GK pickup (not included) and gives you a whole wealth of modelled instrument and amp sounds as well as some wilder sounds you would have thought were unobtainable.
As the GK pickup converts your guitar to MIDI the options are almost limitless including all the major guitar tones from big brands.
You can even change tunings on the fly without having to actually retune your guitar.
Instant access to down tunings, open tunings, 12-string sounds, and your own custom tunings. Analogue guitar synthesizer modelling driven by real-time DSP allows you to play expressive, ultra-responsive synth tones
