Roland GR-700 Guitar Synthesizer

The Roland GR-700 Guitar Synthesizer is a vintage guitar synthesizer from the 1980s. It was used by many famous guitarists, including Steve Vai, Eddie Van Halen, and Joe Satriani. The GR-700 works by converting the sound of a guitar into digital signals, which can then be manipulated and processed to create a wide range of sounds. It features a variety of onboard effects, including chorus, flanger, and delay, as well as a built-in arpeggiator and a sequencer for creating complex patterns. It also has a built-in MIDI interface, allowing it to be used with other MIDI-compatible instruments.
