yep my 25 day old Warwick Bolt-On Thumb bass has a crack on the fret board. the crack is right at the end of the fret board under the E string, were it overlaps the body. i am going to bring it back to GC tommorow to see what they have to say. any one have this problem? any one return things to Guitar Center before the 30 day "guarantee"? i'll keep you all up to date.
