I've used the ID60 head and the ID260 2x12 combo for a few hours each in my friends shop and I'll honestly say they're the best sounding solidstate/modelling amps I've ever used. I really liked the cleans, the higher gain tones were pretty good after some tweaking, but where these let themselves down imo is with the lower gain and crunch tones, just like every other modelling/solidstate amp I've used. They're still lacking a bit in 'feel' in my opinion, but still alot better than others I've tried.
I'm thinking of getting 1 purely for the emulated line out for using on demos at home for when I can't be bothered to drag out a cab and some mics. I haven't used 1 at a gig though and that's the test of an amp for me.
Would I get 1 for home/small gig/demo recording use or as a backup amp: Yes
Would I sell my other amps and replace them with 1 of these for fulltime use: No
