Roland rewrote guitar-tech history with the debut of COSM technology, which first appeared on the pioneering VG-8 guitar-modeling system. Today, the new G-5 infuses a coveted Fender Stratocaster with advanced features realized by Roland’s COSM technology. In addition to offering all classic Stratocaster sounds and functionality, the G-5 provides a new world of electric and acoustic guitar tones recreated by COSM — including instantly accessible alternate tunings and 12-string sounds for all COSM guitar tones! The G-5 also offers a built-in library of coveted modeled pickup tones, and, thanks to COSM technology, also enables unique "ideal-performance" pickups, such as a humbucker with ultra-wide tone and a single coil with full, bold tone.
