Depending on the overall length of your medium scale you may be able to get away with the guitar version (41” inside 45” outside dimensions) the bass version is 9” longer. I have both and use the guitar version for my 34” scale headless basses.i've never had the need for a gig bag before as i primarily record but want to pick some up for a move. will these work for medium scale ? it looks like due to the neck holder position that they should, but maybe i'm missing something
