Orange Rockerverb 50 MKIII All Valve Twin Channel Guitar Amp Head (50 Watts)

The Orange Rockerverb 50 MKIII is a 50-watt all-valve twin-channel amp head engineered for players seeking serious tone and stage flexibility. Built around Class A/B circuitry and powered by 2 x EL34 output tubes, the MKIII combines a crystalline Clean channel with a thick, harmonically rich Dirty channel via footswitchable selection. Valve-driven spring reverb, switchable output power (50W full, 25W half), and built-in attenuation mean this amp adapts to studio tracking and live performance without compromise. The preamp section runs 4 x ECC83/12AX7 and 2 x ECC81/12AT7 tubes across independent channel circuits. Clean channel controls include Volume, Bass, and Treble; the Dirty channel adds Gain and Mid for sculpting saturation and texture. A valve-buffered effects loop sits alongside footswitchable reverb and attenuator controls, while output impedance options span 1 x 16 Ohm, 1 x 8 Ohm, or 2 x 16 Ohm configurations. The amp weighs 20.75 kg and measures 55 x 27 x 28 cm, finished in orange or black basket weave vinyl. Touch-sensitive circuitry responds dynamically to pick attack and playing dynamics, delivering character across both clean and driven tones. Whether used in a bedroom setup or pushed on stage, the MKIII's attenuation means serious volume without demanding cranked speakers, while half-power mode reduces heat and tube wear during longer sessions.
