The Orange Rocker RK30HTC 30W tube guitar amp head from the 30 Series is an all-tube, 30-watt, Class A operation channel-switching head. This tube amplifier combines a single stage clean channel with a three-stage preamp lead channel. The natural channel has just one control (natural volume) that takes you through many shades of perfectly balanced, bell-like clean tones, until you hit the very musical harmonic overdrive of the output tubes. The Orange Rocker amp head's dirty channel takes you all the way from a super clean chime, through many colors of vintage overdrive. Tones that bite like a shark, all the way through to a very fat, harmonically intense, full-on distortion that has to be played to be believed.
