Great amp, not a big fan of the combo myself. They totally rip with a 4x12 or 2x12 sealed back. Cleans and texas style crunch are great on the combo's but I didn't dig the "lead" sound on the combo kinda flubbly in the lows and a lil bit fizzy in the highs when you start adding alot of gain. I good OD or boost pedals helps a considerable amount but they sound SOOOO much better as a head with a seperate cab IMO. Like a few other guys said the combo sounds little boxy unless you can really turn the amp up. I think the graphic EQ is a must too. Mine is my practice/back-up amp to my Einstein. All in all very nice amp and even better when you add a good OD/Distor pedal. Look for a combo with a roadcase and wheels unless your into body building or going to the Chiropractor.
