I got to play an egnator Tweaker head ($399 ) yesterday and loved it. I compared it to a Mesa TA ($899 which I went to buy) and came away liking the Tweaker better IMHO. The Mesa is nice but, sounded bright and thin, next to the Tweaker (both played through the same 1x12 Mesa cab).The mesa has more options and looks better built but, The tweaker blew me away tone wise( great for me classic rock guy). I wanted to love the Mesa, and wanted the two channels. I think I'll wait for the new two channel 40 watt tweaker before I buy anything. There's some great little amps out there.
