The New Roland GR-55 Guitar Synthesizer, Now Available in Black


An electric guitar or bass can only produce the sound of an electric guitar or bass, right? Not with the Roland GR-55 Synthesizer and a GK series pickup. Plucking and strumming on the strings can produce over 900 different tones, and we’re talking everything from grand pianos to the sounds of outer space. The GR-55’s powerful triple-core generator enables you to layer two synthesized sounds, the sound from your guitar’s pickup, two multi-effects and apply Roland’s COSM modeling all at the same time. The easy-to-install and non-invasive GK pickups make it possible to dedicate individual strings to specific instruments, so you can fully customize your unique sound combinations. Sound triggering is lightening fast with zero latency, which is very important when playing any instrument. Pitch and velocity detection is also very accurate for unprecedented response to your performance.

Don’t be intimidated if you’re new to this kind of technology. The G-55 was designed to be user friendly, and features a large LCD screen and 270 presets that give you a grand tour of this pedal’s capability. When you start chiseling away at your own unique sounds, the GR-55 enables you to save up to 297 of your own presets. In addition to its effects, modeling and two PCM synthesizers, the technology inside the GR-55 enables you to change tunings without physically detuning your strings. Dual USB ports let you connect the GR-55 to a computer for recording audio and MIDI information into the music software of your choice. A second USB port is dedicated to playing audio files from attached flash drives, and the GR-55 makes it possible to start and stop the music playback with your feet (the unit features four footswitches and an expression pedal).

Blue versions of the GR-55 and GR-55 with GK-3 pickup were originally launched at NAMM 2012, with Roland announcing a new black version of this wild guitar and bass tone module at the recent Musikmesse 2012 show in Germany. The stealthy new black GR-55 is sold in a bundled kit with a GK-3 pickup for guitarists, or if you already own a GK-3 pickup you can purchase just the black GR-55 on its own. If you intend on using the GR-55 with a bass (the GR-55 features 17 types of COSM modeling and 90 presets specifically for bass guitar), you need to purchase the separately available GK-3B Divided Bass Pickup.
