trying to find out the following;
of the three models, fusion 1,2,and 3 when did the original center block change to balsa?
( i have heard some stories of the guitar with the maple block being too heavy)
also when did gibson introduce the fingers tailpiece instead of the stopbar 1,2 or 3?
(did gibson change the control layout at this time too?)
and finally....when did the neck profile change to the slimmer style from the original chubby job 1,2, or3?
finding much info about this fine guitar is hard man.....
thanks in advance folks
PS ideally i am looking for a balsa block model to save weight along with a slim neck and original control layout......if i have to change the fingers over to a stop tailbar,have you done this mod,is the balsa stable enough for it?
