I have both amps and would take one or the other at anytime, but for some reason I prefer the Compact. I get compliments on both amps, but moreso the Compact over the 330. They each provide different positives. I used both of them chained together last Sunday and almost blew myself off the stage. The BA-330 has raw power; the Compact has an encompassing sound. Don't fight - enjoy what you use!
