Okay...just a matter of curiosity regarding neck attachment schemes. I don't have any U.S. model G&Ls, but I have an LB100, JB-2, SB-3, L2000 and a Kiloton, all Tributes. I noticed that my SB-2 has the four-screw attachment with plate, while the U.S. version has the six-screw attachment. Same with my Kiloton. The Tribute has the four-screw with plate, while the U.S. version has the six-screw attachment. Yet, my Tribute LB100, L2000 and JB-2 all have the six-screw attachment. I have a hard time understanding why the Tribute SB-2 and Kiloton don't share the six-screw setup as do the U.S. versions. Perhaps I would get it if all of the Tribute basses utilized the fours-screw with plate mounting, but they don't. It seems to me that there would be a consistency should all of the Tributes use the same attachment measures as do their U.S. brethren.
I realize that there is nothing inherently "wrong" or deficient in the four screw and plate system...Fender, Peavey and a host of others all use it...and for a while, G&Ls used a three-screw system, if I recall correctly. Just that to my little brain, it seems as though it would have been easier have them all the same--U.S. and Tribute.
If there is a reason and someone knows it...please enlighten me.
