Cool Crossbars are the reason flat-backs fail...

(Or, if the joint does not fail, cracks and warpage will be the result.) Crossbars are the reason flat-backs fail.
Sounds like Job security to me Maestro..

I have seen a new maker doing this still and 'way' over bracing the Back as well. These are not very expensive basses. When they fail, the owners will be 'buying' the bass all over again..

I think a person should be very experienced in making basses before he starts building them. This way, 'mistakes of the future' might easily be avoided..
