For fellow G&L owners...I have a question concerning the interchangability of necks on G&L basses. I have an L2000 and a JB-2, both with the current 6-bolt neck design. I'd like to experiment with trying the thinner JB-2 neck on the L2000; are the necks pretty much interchangeable between the two basses? Is there any difference between the neck pockets, or anything else that might cause problems? Or anything else I should be aware of in general before trying a neck swap? Thanks!
