JTV-69 Neck Specifications?

Recommended Posts

I'm giving my JTV-69 a lot of playtime and was about to buy a new neck until I saw the cost to get specifically what I wanted.  It just didn't feel 'good' to me up past the 10th or 12th, and found many felt the same online. So I decided to give this neck a chance and played the hell out of it the last two nights.  I think part of the problem isn't totally the feel of the neck at those frets but the strings playability.  I'm thinking it needs the truss rod adjusted, for a start.  Two factors might be where I am (Colorado) and where it shipped from, but more so the fact I tune it down half a step.  It seems like the strings are too close to the neck and don't sustain well/die off above the 12th or so.

 

I believe the neck needs to bend in just a little toward the strings.

 

2 things I'm looking for;

  1. Advice on adjusting the truss rod (Korean JTV-69; truss accessible from headstock)
  2. Neck specs just for curiosity and as a reference if I do buy another neck as to what to avoid;
    1. Radius
    2. Neck profile
    3. Nut seems to be 1 5/8.

1. Set-ups are a balancing act between, string tension, truss rod tension, vibrating string length (individual bridge saddle position), string height, and sometimes the nut itself if it's been slotted poorly. It is 100% impossible to diagnose remotely. You need hands and eyes on the instrument, and appropriate tools (at the very least a precision straight edge for evaluating neck relief, with emphasis on precision... in other words an 18" metal ruler that you'll pay $60-$80 for) to diagnose which parameters need adjusting in relation to the others, and to what extent. There are numerous books and YouTube tutorials that can guide you through the basics of setting up a guitar, as they're all subject to the same environmental changes, and they all periodically need the same kinds of adjustments. But trying to guess at what your particular instrument needs sight unseen, is a complete waste of time. The wrong suggestion is guaranteed to make things worse, and may or may not do lasting damage to your instrument. If you're not familiar with what to do, take it to someone who is... any competent local tech or luthier will do.

 

2) Neck radius, profile, and nut width are entirely personal preference... What I might avoid like the plague, you might think is the best thing since indoor plumbing... and neither one of us is "right" or "wrong". If you like the way a particular neck feels and can play on it comfortably, then that's all there is to it. If not, experimenting with the myriad options that exist is really the only way to find out what you like. If music stores ever open again, spend a couple of hours on a Saturday playing a bunch of different guitars, and see what feels good in your hands.

Agreed on all counts. I used to do setups on my guitars myself until I had it done by someone who knew what they were doing. :)  

 

Now that person has moved on after 20 years so I thought I might play a little but will likely try a new Luthier as I need one overall anyway.
