This is a 2023 Fender USA Jeff Beck Signature Stratocaster that has been stamped used on the back of the headstock and declared a blem. With the truss rod nut loose the neck shows very little natural relief as the straight edge touches it at every interval. With the truss rod nut turned counter clockwise to the extent that it exerts upward pressure on the walnut plug the neck will show just a hair of relief. With the truss rod nut very tight the neck will back bow just a little. The neck has a few light marks. I have not had the neck mounted and it may have set up issues. Sold as is.
