OK, so I broke my JAN II despite my best efforts to keep it in one piece. I was at the Bass Centre this morning and bought a JAN I from Chris (the bass tech) He said that the JAN I had to be fitted ON TOP of the base of the JAN III (after filing away the remains of the broken wings) to get the correct height, otherwise the strings sit too near the top of the nut slots. Everything I've read here says you remove the base and glue the brass JAN I directly to the neck. Which is correct guys and gals?

Oh yeah, it's an 06 Corvette 4 string if that makes any difference.

TIA
 
Wondering the same thing man................... :?

How do people remove the base properly anyway ??
 
Just found this. I might get a JAN III when they come out and have done with it.

a penknife or some other small blade.

you just lever it off, it comes away easily.
 
Remove the base of the JAN II and put the JAN I in its place it's fairly easy and will take about 5 minutes to do. All you have to do afterwards is let the glue dry.

I hope the rest of the bass (laminated neck, fretboard and body wings) is glued more securely............. :shock:

The nut is glued very securely. I dare you try and remove it with your hand (I've tried this myself at the factory when asked the same question you are asking now :P), it won't come off unless you use the right tool for removing it. The rest of the body is glued with a different material, because it's different to glue wood to wood than wood to JAN.

It is actually a lot less likely to have a bass break in any of the glue joints, they have proven to be stronger than the wood itself, hence why the laminated necks, part of it is not prevent the neck from breaking with the strings applying so much pressure to it.
 
if you think about it the glue shouldn't need to be very strong anyway as the strings will be pulling the nut onto the neck very securely

That's good to hear; indeed, I haven't heard any case, or seen a bass severed at a glue joint. It would be hilarious though playing bass on stage and "something" falls of...................which turns out to be a body wing of a NT bass..................... :lol:

im not sure "hilarious" is the word i'd use to describe it though
 
Oh Nutz

I just replaced my nut..........the other nut, with a JAN 3. Its too easy. Wood glue and a small C-clamp with rubber ends will secure it nicely.
However you still have to take the strings off in a certain order for now on. I did the experiment and the J3 will lift off to one side if you dont. Heres the order for a 5er:
B-G-E-D-A. Restring from the center out. D-A-G-E-B.
Just before bring the strings to proper picth adjust the J3 to where you see a gap between the bottom plate and the nut. Finish tuning then tweak the nut for your final string clearance.
 
If it lifts off it won't cause any damage to the nut, the instrument or the strings... and if it comes out, just put it back in, it's quite easy. Also it won't change the height at which you had it set before you did anything to it.

You can learn more about the JAN III on our website. Here's the link:
 
You will need to shim the jan1 in order to get the string height right. Otherwise with the screws raised up all the way you will get rattle/the string will still touch the fretboard, I made a brass shim and everything is evry clean and matches... brass shim + epoxy will do the job :)
 
I agree with that "funky white guy". Both my JAN1s are shimmed. :D

+1

I fitted my JAN I on top of the filed down JAN II base. Very solid and no audible loss of sustain.

It was not on stage, it was not hilarious

Over 45º C+black case+direct sunlight+ multilaminate neckthrough + sandwich body construction = some horrible thing.

It was not mine, but I felt very very bad about that pile of wood pieces and oozy glue.
