I have a highway one tele and whether it's a pre-upgrade or post-upgrade is proving difficult to figure out. I'm not sure exactly when the upgrade took place. By my judgement it seems it's mostly likely from june/july of 2005 but there are some seemingly conflicting specs. Here are the facts: -The finish is satin black, and the neck pocket stamp indicates SOL-COL (solid color), but running my serial through fender tells me it's allegedly a 3-tone burst. Not sure if black was exclusive to pre or post upgrade but looking in the neck pocket and under the pickguard suggest it likely wasn't a repaint. -Fender's serial lookup also tells me it is a 2005-2006 and serial dating guides all list the serial as belonging to both 2005 and 2006. The physical date stamp inside of the neck pocket says "June 08 20-" but there is a hole drilled right where the second two year digits were. The neck heel stamp says "July 27 200-" and then a 5 and 7 stamped directly atop each other, as though one was a mistake and one is the corrected number. -Not exactly sure how to tell for certain if the pots are greasebucket (I think they are) but the pickups are on the hot and darker side, suggesting post upgrade. The pickguard is parchment, also backing up the post hypothesis, but the headstock font is 50s style, not 70s, suggesting the opposite. Could it possibly be a mish-mash of pre and post upgrade? Maybe post body and pre neck? Or just a haphazardly assembled frankenstein built during the transition period? If anyone knows of any telltale specs that would clear this up I'd appreciate the help.
