MissoulaGriz and I just had a little blues jam session w/ his Delta Blues and my Classic 30 and 50 (a buddy of mine sat in on my C50 for a nice 2 hour 3 Les Paul jam). I'll be damned if the 3 amps didn't all sound about the same!
The Delta Blues 210 was a little tighter and punchier than the Classic 30, which was a little warmer I'd say. Both sounded great. You really can't go wrong w/ any of the Peavey Classics or the Delta Blues from my experience thus far...
Having both the Classic 50 and Classic 30, my bases are pretty much covered - but - if I were to go with one amp to use for home and gigging, that Delta Blues 210 would be ideal.
