I just bought a Gator case for my Mustang. I had to move the padded neck rest cross slightly forward (toward the headstock) but I didn’t have to drill any new holes, just remove the screws and move the foam block forward and replace the screws. It just needed a bit more room because I have a strap lock on the upper horn. I haven’t moved the little cubby hole hinged top thing yet, but I can if I want to later. I really don’t use those things anyway.
The only marking or item # is GWE-ELEC. The case is 42.5” inside length, Black Tolex covered fiberboard. I could not find this case listed on the Gator website. I took my mustang to the shop and test fitted so I was 99% sure it would fit. I did the mod at home. The retail price was $79.99.
Another shop in town offered to order a G&G case with the Fender name plate. List price is $299.00, so even with a discount offered, its ridiculously over priced IMHO. I don’t want to advertise for Fender, I just want to keep my bass in a HS case.....
