I'm presently using a Peavey Tour 450 into a Peavey Headliner 410 cab. I'm looking at upgrading to a tube head, probably the VB3 and was wondering if I should go to the Tour cabinets at the same time. Does anyone know what the difference between the Headliner and Tour cabinets are? Looking at Peavey's website, I can't quite get a good idea. Thanks. I'm using a 2011 Fender American P bass if that makes any difference.
