I have my HP now and really love it. I've had a difficult time finding an amp and this one is a keeper.
as far as the "more headroom" from HP to HP2, can you comment on the players impression? do you feel its... 15% louder? 20%? 5%?
I'm loving my HP for now, but really would prefer a brand new amp. I have a friend who already wants to buy the HP from me, so i could sell it and upgrade to the HP2 when i'm ready.
but i honestly don't think i need to. my used amp came with an awesome hard case, the wireless footswitch, and it sounds freakin awesome.
