EVH 2253060000 5150III 50W EL34 Tube Head with Dual Concentric Controls (Black)Independent volume and gain control for all three channels have arrived with the EVH 2253060000 5150III 50W EL34 Tube Head. You can experience total control, along with the same lethal looks and ferocious EL34 tone of the 100 Watt head. The EL34 power tubes deliver signature harmonic overtones, with more dynamic compression and saturation that evoke a more modern British sound, all with the sustain and versatility expected from EVH 5150III amps.
