I just picked up a Mono bass sleeve and I must say I'm impressed with the quality and level of protection. For a lightweight gig bag it's quite rigid and looks to offer excellent protection all round. Side handle and straps look long lasting. I have 2 Fender basses, a P and J and both fit in just fine but the only concern I have is how tight the case seems at the body end, specifically over the volume and tone control knobs. It does seem quite a tight fit. Do any other Sleeve users have any experience of this? I presume it was tested with standard size basses and all will be fine ?
