Unlimited Sonic Possibilities
The new GP-10 puts a universe of amazing tones and tunings at your command, all in one compact processor that’s affordable and easy to use. With a Roland GK-compatible pickup on your guitar, the GP-10 lets you transform your sound into numerous classic electric and acoustic guitar types, basses, and even analog-modeled synths, including the legendary Roland GR-300. Not stopping there, you have access to instant altered tunings, including popular open tunings, 12-string tones, and “down” tunings that are essential for today’s ultra-heavy rock styles. The versatile GP-10 also functions as a full-featured multi-effects processor for both GK and normal pickups, giving you a huge selection of COSM® amps and effects for live playing and studio recording. In addition, USB connectivity lets you capture GP-10 tones directly into your DAW, and you can even play computer-based soft synths from your axe with the GP-10’s guitar-to-MIDI convertor!

- Instant access to down tunings, open tunings, 12-string sounds, and your own custom tunings
- Instrument modeling powered by COSM technology, including conventional electric, acoustic, and bass guitars, plus sitar, banjo, fretless guitar, and others
- Analog guitar synthesizer modeling driven by real-time DSP allows you to play expressive, ultra-responsive synth tones
- Create totally new sounds by blending modeled and normal guitar tones together
- High-quality COSM amps and multi-effects derived from the GT-100
