The Marshall Vintage Modern 2266 nails vintage plexi style tones with it's KT66 power tubes. Then switch to the modern channel and it gets plain nasty. Bar none, I believe it is one of the best Marshall amps produced. I wouldn't consider it great for metal or the cleanest of cleans, but just about everything else can be easily achieved. Classic Marshall crunch!
All my lovin' goes to this amp. It's my main amp and it kills, it's been nothing but reliable and I've had it over five years. Still my main studio and live amp. Kills it for lead, takes pedals well. Actually very versatile with the two gain shapes.
