I asked Borris this just a week or so ago (he owns 7 Bajas I believe). He said basically there have been no changes to specs at any time that he knew of. I asked because I had read a post that stated the early Bajas had more of a fat C shape vs the V that the Baja is specd for. Another rumor at the time was that the pups were custom shop pups, placed into a MIM fender. Do you have any photos of the new "deeper" butterscotch? I wonder if the neck is not as dark simply because our first year teles are have had time to age a bit, vs actually being stained darker. BTW I put my Baja out in the sun (not hot out though) several times, maybe 10 hours a week for a few weeks. The neck darkened a bit, the body almost not at all though.
