I used a MKII for close to 10 years in a punk/hardcore band.
It really liked it. Ch2A does a good "hot 800" tone that is tight and punchy. 3A was similar to the highest gain channel on the Duotone....so again modded Marshall territory. 3B gave me Recto and Uber vibes. A bit leaner than both, but no fizz and fairly tight.
Feel matters to me and I found the MKII very easy to play.
Would I own one again? For the price a Mk1 or Mk2 sells for, absolutely!! They are alot of amp for the price.
The downsides: Amp has an overall "hi-fi" tonality that some may not like. It's top end and upper mids sit different IMO. So if you own a fleet of great amps, it isn't going to replace them. But maybe it could be a good, well priced "do all" amp for gigs and jams.
And this is for the MKII....I never played a mkIII but a friend owned one and took it back within a week.
