Folks don't need a diagram . Around 93 - 94 Tune production was moved to Korea, if your 1999 date is correct its Korean.
That's why I'm so curious. The 99 date was just thrown out there. There's really no history on the bass at all.

Japanese production, maybe 3 to 4 years. 2 of those years, assembly from Korean parts.
Korean production, 27 years and counting.
What's the chances it was built in the few short Japanese years against the much longer Korean run ?
I doubt you'll ever know so just claim the country of origin you prefer.
The site I took that from is Tune Guitar Technology.Just by the diagram you can tell it's a Korean Hatsun? I can't find a serial number anywhere on this thing. I have a few more pictures a few posts up.

Made in Korea, assembled in Japan, makes no difference to meI'm just interested about my bass is all.
Just as a note my MIJ Phoenix has the serial number on the inside of the control cavity cover. It's there; just hidden. I am not sure if this applies to the earlier MIJ Tunes though.Japanese Tunes have all numbers or nothing at all.
Korean Tunes start with an "S"
No they don't all have that diagram,
Korean Tunes have the TWB diagram on the website.

So, I recently have been casually hunting for semi hollow fretless 4 strings,and came across one of these used online. I’m not really sure it’s this exact signature model, but it looks very similar. Piezo only.Hello everybody! Here is my WB4 Massimo Moriconi signature. Hollow body, piezo pickup only, three band eq, strung with D'Addario black nylon. Light weight and feather smooth neck. Sounds actually great!

Thanks for the detailed and thorough response,Kirk!Hey @woodyng2. The nut sizes on Tune basses are pretty normal. I’m certain that’s a typo. There’s no way it’s even close to 2”. I didn’t find the exact sizes when I searched.
But, think Jazz bass neck in feel and size for a 4 string, probably 1 1/2”. My two 5 strings are between 1 5/8” and 1 3/4”. The necks are fast and thin. As far is this being Built in Korea, you do the bass and the country a disservice assuming it’s anything but a solid well constructed instrument. Also with excellent hardware and components. I think these retail for about $1000-1500. Depending on fancy tops etc. Their preamps are excellent! I’d compare them in sound and quality to Bartolini. The voicing I find to be much more to my liking and preference than, for example, the Aguilar OPB3 which I’m not a fan of. Again similar to a Bart Pre. As are the Pickups, also similar to Barts. All the Korean ones I’ve tried have been Mahogany body’s that are lightweight and resonant. I’ve never had the pleasure of playing any of the high end fancy wood ones. The bass above weighs in at 8.8 lbs and my other TWX5 is 8.6 IIRC. All in all, on par with the $1k-1.5k Ibanez basses. The string spacing is 18mm I believe, as opposed to Ibanez tighter 16.5. So a little closer to a fender 19mm, I’d call it comfortable and not cramped, like I feel on an Ibanez.
To sum it up, I personally would definitely pay the $800 if that’s what I was looking for. As a matter of fact, I nearly bought that beautiful blond fretless five that’s in Japan for $800 before I saw this one and figured I could have it made into a fretless for a a couple of hundred less.


Thanks for the detailed and thorough response,Kirk!
I was buying the bass online from GC,and not getting any response to email or even direct calling the store.
“Sure,we’ll find out and get right back to you”....2 days later,still nothin’.
I decided since they have a moneyback guarantee, I’d just chance it,and bought it.
Glad I did.
Bass was advertised as in “fair” condition,which was my chief concern.
Got it yesterday,and overall physically, it’s not bad at all. Missing the headstock logo,and a few of the knob tops on the Alembic style knobs,and a few very minor bumps and bruises.
The piezo pickups,3 band preamp all work fine,seem to be set flat internally. (Likely factory settings.)
The bad news is it had a very heavy set of flatwound strings on,and a big bow in the neck, almost unplayable.(requiring major effort to press string to wood.)
I took it to my guitar guru to see if it was salvageable,and fortunately the trussrod and bridge had plenty of adjustability. He cleaned it up, put a new set of Labella White Copper tapewounds on it, and has it set up perfectly!
It does indeed have a very narrow slim 5-piece neck, j bass-ish, just perfect for me.
I have since found out these are Japanese made, and retail for $1700, which justifies the asking price. I have no issues with Korean made basses,my point before was that such would likely be a $800-1k bass NEW,so the price seemed high for a used “fair” condition bass.
This is one of the fancy wood models you mentioned,a mahogany body with bookmatched
flamed maple top and headstock cap, and a really gorgeous rosewood fingerboard.
Looking forward to getting it home and seeing how we click.
These are “before” pics.

From the same website, if you go to the SHOP page, it has that particular model (wb4-fm)They have been a feature of the Korean product range for quite a few years.

Sorry!I've been passively eyeing that bass on GC for a little while now but really couldn't justify another bass purchase this year. Glad that the neck issues were solvable! I'm sure that it's gonna play and sound fantastic now!
Thanks for correcting meFrom the same website, if you go to the SHOP page, it has that particular model (wb4-fm)
listed under a “Made in Japan” banner, with a price in USD.
Good news is that you can find replacement knobs like the originals from a few outlets (one in Canada, and one in Korea if I recall).Thanks for the detailed and thorough response,Kirk!

The knobs are very similar to Alembic “collette” knobs, which at $25 apiece, I will have to pass.Good news is that you can find replacement knobs like the originals from a few outlets (one in Canada, and one in Korea if I recall).
Or you can replace them with super cool wood ones from fine folks on Etsy like Invalid Link Removed!
