A friend of mine who owns a 70's Mustang was telling me he had to much neck bow and I said ok we can just adjust your
truss rod, but his mustang does not have the typical opening at the headstock like I thought it would! What I did notice is you can see his truss rod at the other end next to the
neck pickup along with two slits in the truss rod itself. Is there a special tool you need to adjust or will a flathead screwdriver work? Thanks!!!!!
