The Crush 20RT builds on the tonal platform of the Crush 20 with even more functionality due to the inclusion of a lush onboard reverb and an integrated chromatic tuner. Like its more ‘stripped down’ sibling, the Crush 20RT features footswitchable Clean and Dirty channels plus our new high gain, four stage preamp design, serving up a huge palette of overdriven and distorted sounds, rich in harmonic overtones.
