For guitarists who don’t want to deal with a computer and Jam Origin’s MIDI Guitar, or a hex pickup-based system like Fishman’s Triple Play, or Boss’ own GR line, the SY-300 Guitar Synthesizer seems to offer a viable alternative. It also appears to provide a faster, latency-free tracking, as it doesn’t use MIDI. More than a processor, though, it creates real oscillator based sounds. Mitch Gallegher’s Sweetwater demo provides a good overview, but I hope to get one in soon for an in depth look.
