The Orange Crush 20RT 20W guitar combo builds on Crush 20's twin-channel tonal platform and feature layout with the addition of lush digital spring reverb and on-board chromatic tuner. Create huge dreamy reverb trails perfect for soundscape effects or add subtle hints to make your lead lines shine through. And, with Orange's CabSim technology, you get an emulated 4x12" cab tone through the headphone output to give you huge sound even when you're practicing silently.
