I have a "Road Runner" acoustic gig bag. It has pockets for pedals and cables, papers and books and it has straps for carrying it on your back as well as carry handles.
I got mine for free when I bought my bass from the pawn shop. They advertised the bass as coming with a case but they didn't really have one. So I twisted their arm til they gave me a case. As it was a shortscale bass they put it in an acoustic case and I walked out happy.
When I got home, the bass got put in the closet and my acoustic got put in the new case.
