Honestly Don..I'd much rather use the mic thru the KB which would allow less crap to setup on small gigs and when I get a chance I'm not ruling it out as of yet as I need time to sit down bring the S970 in the house and dig into the EFX and try to come up with the right combination of settings and locks to preserve it too..The Pa4x certainly bring more to the table...dont forget I had a Pa3x also just sayin
