The G20R is a single channel 20W combo featuring a high performance 8 in. speaker and front panel switchable overdrive. Treble, middle and bass controls allow precision tone shaping, and a built-in spring reverb with its own dedicated level control gives that big-venue ambience just when you need it.

Other pro features include a retro illuminated VU meter so you can check your output level, a front panel headphone output for silent practicing and a line output for laying down tracks in the studio.
