If you fully crack the gain and shift the mids, I find you can get a pretty fun distortion but perhaps not usable in a band situation. Doing the opposite to drive the output stage it's a lovely warmth fuzzy, but too loud in most of my situations!
As Wasnex has said, it's definitely more of a cleaner amp. Can say honestly it handles pedals and hot signals very well. For heavier parts in songs I have a cranked DG X7 and the sound could take down a house.
That's a really nice and clean example, but if you don't know the history I'd consider getting it checked over due to it's age.
