Zuki.... Oh no!!!
Buyers remorse setting in?
Maybe it's too soon to tell what is actually the problem? I know your so used to the Pa3x, will you play a few more gigs with the Pa1000 and see if you'll keep it? or, just forsake everything and get a Korg Pa4x and be done with it and go for the gusto like Steve M says?...
I commend your efforts it's rough in the trenches changing gear your used to playing and have a comfort zone, I've been there buddy get back on the horse you can do this good luck.....
