Ade Emsley – Technical Director
When the original Rockerverb was introduced in 2003, everyone really liked the Dirty Channel – especially its mid-range crunch – so we kept it the same for the Rockerverb MK II, which was available as a 50 watt and 100 watt head and 50 watt combo. But we decided to make the Clean Channel more versatile by adding a Middle control. The reverb was made more defined and controllable by adding a 12AT7 tube; also, the effects loop was even more transparent than in the MKI.
The MK II ran on a pair of EL34s and had the same switch on the back that the old RV100 did, so you could run it on 6L6s, KT88s or KT66s. The RV50 MK II was available as a 1×12 combo, and also a 2×12, featuring a redesigned cab where the control knobs were at the front.
