Plus, with the new Patch Link function, you can alignGR-20 Patches with those in a MIDI-capable externaleffects processor like the BOSS GT-6.

Whether you want to adjust the preset Patches to suityour preference or tweak them to fit the vibe of a particular song, the GR-20 makes it ultra-simple.There are five dedicated knobs for editing attack,release, chorus, delay/reverb and level. This makes experimentation a fast, fun and menu-free process.

Your feet are a big part of the action with the GR-20’sbuilt-in control pedals. The Expression pedal can
