had my first gig tonight with my SWR WorkingPro 400 and Avatar 2x10 Kappa Pro. I'm in love.... it filled a medium-large room with around 150 people AMAZINGLY, and sounded great with my Ibanez. i was playing full band, with drums, guitar, and vocals. and i thought i'd have volume issues... definitely worth every penny. especially since i'm not ready to put out 2k just for an amp. $900 is a steal for both.
