I have a yorkville bm400 and I was wondering if an Acoustic 450 head has as much volume as the yorkville. I know that the acoustic head has less wattage but I heard in reviews that they are really loud. The cabinet I'm using right now is a 1x15. Any personal info on the acoustic 450 would be great. oh ya, does the Acoustic 450 have enough volume a decent size club w/ P.A. does it get drowned out by a drumset and a Reasonable volume guitar.
