So the neck relief on my Tele is too much around the 8th fret, when fretting at the 1st. I even purchased a notched straight edge which confirmed. I attempted to tighten the truss with the Fender issued allen key and it only turns counter-clockwise. When attempting the lessen the relief (clockwise) it turns a tiny bit and then locks up, and with added pressure the key slips out. I have tried loosening it up with PB Blast/WD-40, I even purchased a tool from StewMac for stripped nuts. Nothing seems to do the trick. Researching this forum, I found a few users mentioning that the depth of the nut on the truss is not standard on the Hwy1s. Any truth to this? Anyone have suggestions for correcting this issue?
