Question: Is the Incase dub bag made like all other aftermarket bags/cases? As in they are made to put a Fender P/Jazz 'standard' bass into. I have been looking at this bag and like the idea of carrying the bass and backup into a bar or wherever you play versus two hardcases banging everyone around. I use Spector basses and have found they tend to slide around in a 'Standard' case. Are there provisions for snugging up your bass once inside the Incase bag? Anyone use the incase with a non-standard type bass? Thanks.
