Hi all, I've bought a B-stock Sire Marcus Miller Z7 5-string for £470, pretty much as new however there is a problem with the volume/tone knob (I suspect it's a return and they didn't fix it prior to sending it out to me), they move in sync and are basically attached together, please see the below video. As I managed to get it for a decent price I'm wondering, is this something that can be fixed easily? Or should I just return it and get my money back?
