Going from full gain and winding back gives you a variety of classic Orange tones. Whether you're looking for metal, fusion, blues, rock, or even country the Rockerverb 50 MK II doesn't fall short.The Rockerverb 50 MK II also comes standard with footswitchable reverb and an FX loop.Check the drop-down menu to the right to select colors and/or other options.FEATURES50W4 ECC83 preamp tubes4 EL34 power tubesAccepts EL34, 6L6, KT88, or 6550 power tubesClean channel controls: Volume, Bass, Middle, TrebleDirty channel: Gain, Bass, Middle, TrebleReverbFX loopSPECIFICATIONSRockerverb 50 MK II 50W Tube Guitar Amp Head21-3/4"W x 9.5"H x 11"D44 lb.
