Alright, I now LOVE the bass! The neck took a week or so to convince me that it is indeed a nice profile
Current spec:
-Shielded cavity,
-250k Vol // 500k Tone // .047uF cap,
-vintage knobs,
-AWESOME Pickguardian 4000 clear plexi // backpainted guard in 2015 hole pattern (PERFECT fit; absolutely NO modification needed),
- Kalium (Circle K) balanced tension strings (.094-.039),
-Dunlop Straploks (be sure to drill and dowel current hole with .125" material; this is completely reverse-able for drilling back out for original strap pins, which are quite low-quality in my opinion)
Modifications in-process:
-original '62 truss-rod cover (clear plexi // backpainted - it's a GEM),
-new RIC Horseshoe,
-Audere hum-cancelling module and ultra-transparent preamp (prototype, and specifically for the HS p/u)
VERY happy with this bass, even if it's apparent where they cut corners: thin chrome plating, low-quality plastic for original truss cover, swirly finish under the clearcoat.
What they got right: dead straight neck, PERFECT fretwork, bridge-pickup-string alignment is PERFECT, original pickguard neck p/u route is spot-on.
Developments from vintage basses to modern that I like: Tilt-back headstock (they had to lengthen it in order for the frontal profile to remain cosmetically coherent, and it looks great in my opinion), thinner upper horn, easier access to upper register (they moved the scale {bridge / nut} up in order to align the 20th fret above the body joint, a la the 1969 21 fret 4001's), MORE NECK THICKNESS IN THE NECK PICKUP CAVITY (vintage basses ~10mm, this one ~19.5mm).
Developments needed: Shield the damn cavities! Use very rudimentary, entry-level electronic science to cancel this gawdawful hum! For eff's sake, it can be done, with several solutions to that issue. My 1969 Norton 750 Commando has electronic ignition. Updates don't always need to compromise or otherwise spoil the vintage style that sells the product.
I understand that these developments may have been out for a while now, but I have been under a rock. The most modern RIC or Rick I have ever owned was a 1996 4003, but otherwise was 1973-1979 4000/4001 basses.
