100 HX. I originally bought the 60, but I own a Nectar Pacer MIDI foot controller that I use with Logic and Amp Sims. The only way I was going to get it to work was to buy a MIDI host box that cost more than the price difference between the amps. With the switchable output I can sit in front of a 100W amp and enjoy playing, without waking up the kids.
I think they're great! You'd pay almost as much for a powered speaker cab - and it does that as well.
6 amps, 6 reverbs, 18 effects. Effects loop. MIDI control. XLR out.....and so on. Everyone has a gripe about foot pedal control - and, if I didn't have the Pacer I would agree. But - the Catalyst Edit app is so very useful. I hit my loop pedal, play in a section of a song, dial in a sound, save it as a preset and that's it! My only qualm is the absence of bluetooth - I'd love to have a tablet on my mic stand and change my presets wirelessly.
I certainly wouldn't judge them by factory presets - that stuff is for music store tyre-kickers. Slip into manual mode, twiddle some knobs and you get a real feel for the versatility and usefulness of the tones available. If you really spend the time - esp. with the app - you can craft some very fine sounds.
It's a huge amount of high quality sound and gadgetry for not much money. Plus, if I ever want to repaint my studio, the 100W would strip the walls if I cranked it right up!
