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.
