There is nothing really unusual about a heel located adjuster - that was the original design that Fender started out with
When I hear the description "vintage Fender neck" or "vintage-style Fender neck", I still picture a neck with a single rod, single-acting truss-rod with a heel adjustment.
The adjuster has a " + " shape to it that looks like a philips head, but isn't - it's just two intersecting slots
Adjusting it wasn't really considered a big deal "way back when", because the adjuster isn't completely covered - usually you can turn it by getting a bite in one of the slots at a time with the right screwdriver or a specially ground one like
@Timbresmith1 mentions - worst-case scenario involved removing the pick-guard
Some folks (including myself) sometimes used an old-style paint can opener modified with a couple of file strokes so it would engage the adjusters slot so you could make a quarter-turn without scarring-up the pick-guard
And, there will always be some folks who believe that heel-adjust truss-rod design is part of, or contributes to, the "magic" in the tone of the vintage Teles
I’m going in with an open mind. I love the feel of the v neck. I have vintage style tuners so I’m sure this neck will work out. I have gotten some good advise so I’m looking forward to it. It just threw me off a bit
