Does anyone else find that their Warwick bass simply doesn't fit well in the flight case? I have a Corvette Standard, and even with the foam pads there is still plenty of room for the bass to move around. After a month or so, I noticed that every time I opened the case, the pad towards the lid would be completely flat. I then started 'rotating' the pads, and now both pads are flat and even after leaving em out a for a while, they remain flat. Now the padding on the walls of the case are beginning to flatten out and dent as the bass is simply moving around way too much in the case. Has anyone else experienced this? is it normal?
