The Orange Rockerverb 100 MKII is an all-tube, channel-switching guitar head with a wealth of classic British tones and unparalleled versatility and is a great update to the original. The MKII version has a more transparent FX loop, a mid-band EQ on the clean channel, and a bigger reverb with an additional tube to drive it. The two-stage clean channel of the Rockerverb MKII head chimes and sparkles, but when pushed to the top of its range emits a natural power tube breakup that'll bring a tear to your eye. This non-master channel is deeply rooted in the tone of vintage Orange amps and plays particularly well with pedals. Switch over to the dirty channel for singing, harmonic drive all the way through modern metal distortions, and tame the output level on high gain sounds with the volume control after the gain stages. Wanna change things up a little bit? The Rockerverb MKII lets you swap the stock EL34 power tubes for 6L6s/KT88s/6550s to completely morph the personality of the amp -- just rebias these tubes and you're ready to roll.
