My BTB33 has been doing fine in the ATK1000C case. I use a little bit of soft foam to wedge it in so it doesn't move.
You can literally take a mallet to it.
Use a small board to buffer the mallet from puncturing the fabric & just whack the foam down.
I've bought Peavey cases before & whacked the foam into shape to fit a Fender.
Wow! Thanks for the quick replies guys, and thanks for quashing the sudden onset of fear of damage to my hard earned cash investment. I expect Ibanez felt it necessary to fix a potential bad mark on it's QC.
Thanks again!
