Hey Rick, all tube in MP2, no SS voicing. Also in MP1 compressor was only available for SS voice, not for clean or dist tube. In MP2 everything is available for all voices except OD2 is only available for voices 6 through 10 (the high gain voices). So the voice I currently use for most everything (5 Warm Vintage) has only OD1, which I find is plenty of gain (for what I want/play, even with volume knob at 2.5 to 3). With some experimenting, I'm confident you'll find the sound you want.
@Dante, don't know about spanky clean being sort of equivalent to MP1 SS voice (never tried it (yet)) but you may well be right. While the MP2 is a very different beast to the MP1, they did attempt to kind of include the MP1 sound in the MP2's boundless sound possibilities, e.g. there is a "MP1" factory patch.
With MP1 I used the SS voice for clean sounds (don't think I ever used MP1 clean tube voice ?), so far in MP2 I've always used 1 Crystal Clean for clean sounds. But partly egged on by this discussion, I'm going to try every factory preset (which I've never done) and also the cleaner end of town (voices 1 through 5).
