Roland | GR-20


Ever wanted to thicken up your guitar sound with a warm synth pad? Or how about a screaming lead sound that puts you in front? The GR-20 Guitar Synthesizer makes playing high-quality synthesizer and instrument sounds from your guitar as simple as 1-2-3. First, attach the included GK-3 Divided Pickup to your steel-stringed electric (no drilling necessary). Second, select the type of sound you want using the Bank knob. Third, choose a sound variation using the Number/Value dial and start playing. With the GR-20, it’s easy to tap into the power of guitar synthesis.

The GR-20 now offers a new GK-3 and GK-3B Divided Pickup for guitar and bass players. The newly designed GK3/GK-3B has a slimmer, more ergonomic design for virtually any guitar or bass guitar. The GR-20 offers two modes. Guitar Mode and Bass Mode to accommodate the different ranges and allow for faster tracking. The GK-3B can also work with 6 string basses as well.

Velocity As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key. Aftertouch Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.
Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise.
