What can I say? The Rockerverb's reputation precedes it and that is for a VERY good reason. The pics only aesthetic is classic and timeless (really looks great with a matched Orange cab).
The clean channel is very glassy and round with lots of headroom and plenty of punch - breakup is smooth and beautiful when the volume knob is pushed. The RV's cleans are not quite as chimey as Fender or Vox and I actually much prefer them over Fender and Vox. This is subjective, but I find the cleans much more pleasing to the ear and much less 'shrill.' Many people try to compare Orange to other brands and the fact is, you just can't. Orange has a very distinct tone which is what makes them unique! They aren't trying to be something else - they are Orange.
As many have said before, the dirty channel is where this amp really shines. I used to have an AD30 and while it is also a truly great sounding amp, it just didn't have that 'special something' that the Rockerverb most certainly does have. The gain is just incredible - very tight low end, lots of midrange punch and very shimmery highs (again without being shrill). Quite simply, it produces one of the smoothest and most 'musical' sounding distorted tones I've ever been lucky enough to achieve and play.
The attenuator, complemented by the 1/2 power and 2/4 power tube switches make it usable in any situation from the bedroom to very large stages. As some may have stated the tone loses some of its luster when the attenuator is pushed to extremes (especially at 1/2 plate voltage) but it still sounds awesome.
I generally don't use much reverb but it sounds great to me and is very usable in band situations. It doesn't have a super long tail like some fender verbs but IMO those only throw mud in the mix.
This has been my dream amp for many years and I am glad I held out for the MKIII version. It looks great, and most importantly sounds amazing. If you're looking for an amp that will cut through with outstanding tone, clarity, versatility and punch, this is for you. It may be on the expensive side but it's worth every penny. I don't think I'll ever buy another amp after this one - if I do it will be another Rockerverb!
