Beautiful guitar spoox. Is that back one piece? Fantastic. Congrats on one heck of a good deal.
Apologies for the buttt-inski but I believe F412's have an arched laminated maple back "by definition". The only exception I can think of is the earliest F512's were labeled "F412
special".
But the 2 "outside" layers are single sheets of maple veneer, with in inside "bulk/stiffness" sheet, larch was mentioned as being used in Westerly for example.
An interesting detail, in Westerly at least, is that the veneer sheets were acquired in lots that were typically sheeted from a single flitch, so the grain of any 2 consecutive sheets is almost identical. Allowed 'em to position the inside and outside sheets so that it looked like one piece, the grain matches inside and outside on inspection.
Since they glued up the sheets into laminations in house in Westerly before putting 'em in the archback press, it was easy to make sure to match the grain on the tonewood veneer.
Actually don't know if they did that in Tacoma, but I got a suspicion they would.
Yeah, very nice piece, Spoox, congrats!
You already answered my curiosity about whether it's a 1 or 2 truss rod build, and '06-'07 seems to be when it happened.
But speaking of the backs, I realized there's a
new question: does the inside and outside grain pattern match on the back?
