The Orange Rockerverb MK II 50C offers improved functionality over its predecessor, but the tone remains unchanged. Mid EQ control on the clean channel, more transparent FX loop, and a more usable reverb with an additional ECC83 preamp tube to power it giving you added control over tone. The Rockerverb MK II 50C is an all tube, channel-switching amplifier with ultra-transparent effects loop and valve-driven reverb. This amplifier utilizes a two stage clean channel with a four stage dirty channel.The clean channel delivers a super rich clean tone with beautiful harmonic overtones. Much like vintage Orange amps, the clean channel is a non-master channel. When cranked, the power section breaks up faster, delivering the most classic British crunch imaginable.The Dirty Channel is four stages of unadulterated filth, but its no one-trick pony. Move the Gain knob from 0 to 10, and as you do youll find a variety of Orange tones, from metal to fusion, rock to blues, theres even some country in there.All 50W Rockerverb Mark II amps offer switchable output tubes. This means you can swap the factory fitted EL34 output tubes to 6L6s, KT88s, or 6550s. Just make sure you take your amp to a tech for rebiasing!
