It does however appear to be a rather nice BB1000. Probably a genuine mistake as the owners manual covers the 800-1200 series.

What you need is one of these - [url="http://www.simscustom.com/pickups/4string.html"]http://www.simscustom.com/pickups/4string.html[/url]

This article on setup by Sadowsky gives some examples of string heights - [url="http://img.guitarchina.com/img2010/0901gc/01.pdf"]http://img.guitarchina.com/img2010/0901gc/01.pdf[/url]. In the end though it's all down to personal preference and what works for you. Neck relief, levelness of frets, string height, string type/gauge, height of pickups, how you play (finger, pick slap, light touch/digging in etc) all work together when setting up. Every bass responds differently and finessing each of these elements is the trick to finding the optimum setup for your particular bass.

The Korean license adjustment screw takes a 2mm hex wench, the US version takes a 1/16".

Crikey, haven't a clue! I would expect metric. Just off out but will check my JO4 and post tomorrow unless someone (else does first)

The licensed ones on Korean Laklands are excellent. I also have a US set and can't see much difference except for the logo. In fact I prefer the licensed ones as they have a tapered shaft (although this may be specific to Lakland)

These look to be 1982 Fender pups (middle two digits refer to week, last two digits to year)

If it's a dual action trussrod then it should just pull out and be fairly easy to replace, But if it's a standard rod (which it looks like) it will be anchored at the headstock end and replacement is a major job. One option would be to cut a recess in the neck heel as in the pic below. This might give the spoke wheel some fresh threads to grip.

Definitely a zero fret if you zoom in. Maybe it's been defretted? Either way an adjustable nut is a bit pointless with a zero fret (or vice versa)

Can you describe the sound from the 'dead' notes or post some clips? For example, is the fundamental note missing (or weak) but some of the higher harmonics still present? This is a common symptom of a dead spot where the resonant frequency of the neck at that exact spot happens to coincide with the fretted note - this sucks the life out of the fundamental but leaves some of the higher harmonics intact. Or is the note full bodied but just lacks sustain? The fact that increasing the effective mass of the headstock doesn't improve matters suggests it's something other than a dead spot.

Did it work before? If you turn the neck vol full up and then slowly turn up the bridge pickup does the overall vol progressively reduce to zero? If it does then it sounds like the hot wire from the bridge pickup is being shorted to earth somewhere. If you have a multimeter that should be pretty easy to trace. Posting a few pics of the wiring might also help.

Not sure what sort of projector your using but this site sells 6" and 3" oil wheels - [url="http://www.optifanatics.com/Browse.aspx?id=22"]http://www.optifanatics.com/Browse.aspx?id=22[/url]

If you manage to test this it would be great to hear some sound clips. Particularly the multiple series switching options as I've not seen these offered on any other stock bass.

Here's a rather unique Legacy Elite 5 fretless. An unusual single pickup version built in 1988 for a well known UK pro player and used on many sessions and albums. Flamed koa top over poplar body. EQ has been professionally replaced with a Stingray 3-band (original pro owner prefers the SR frequency centres to the stock Zon eq). Sings like a bird. A bit too much for me to be honest, I'm more of a plunker! Will be putting it up for sale shortly. I feel more at home on an old P or J these days (getting old!)

Here's another schematic for the Enfield Super 8 pickup - [url="http://www.enfieldguitars.com/Enfield%20instructions%20page1.pdf"]http://www.enfieldguitars.com/Enfield%20instructions%20page1.pdf[/url] Not tried one myself so can't comment but I'm sure there's a pretty wide spectrum of sounds on tap with all those different coil combinations. All the switching options shown here are also parallel. I'm not sure why they don't offer series switching options as well. I've tried Stingray HH and HS models but actually much prefer the single H config. The other coil combinations sounded different but, to my ears, the single H setting still sounded best. More direct and punchy than the other coil combinations, some of which were a bit too scooped and polite for my liking. Who wants a 'polite' Stingray? Enough people to carry on making them I guess! What do I know

The Babicz is another drop in replacement worth considering. It achieves much better coupling with the body without adding mass (it's about the same weight as a BBOT). [url="http://www.babiczguitars.com/full-contact-hardware.htm"]http://www.babiczguitars.com/full-contact-hardware.htm[/url]
