This is my first proper decent amp that's not a combo. I bought it second hand from a guy along with two cabs, a 4x10 and a 2x15. The 2x15 is my favourite, it gives me that lovely low-mid punch and growl that I love.
The head itself has given me a bit of grief. For quite a while I suffered through it being really scratchy and poppy, and there were times where it didn't even work at all. Not long ago I took it to a guy to get it fixed. He replaced the gain and master pots (had to specially order them from the states and this one uses low profile pots) and now it sounds a treat.
Only downside to this is that it weighs a metric fuck-tonne.
