Orange RK50C112 Rockerverb 50 MkII Guitar Combo AmplifierAll Valve, 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. It is a non-master channel, much like vintage Orange amps, and 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 it is NOT a one-trick pony. Move the Gain knob from 0 to 10, and as you do you’ll find a variety of Orange tones, from metal to fusion, rock to blues…there’s even some country in there.All 50 watt Rockerverb Mark II amps offer switchable output valve’s. This means you can swap the factory fitted EL34 output valves to 6L6′s, KT88′s, or 6550′s. Just make sure you take your amp to a tech for rebiasing!Features a 12″ Celestion Vintage 30 speaker.Features:
