First of all, I am neither knowledgable about guitar construction, nor guitar set-up. I bought my US JTV- 69 in 2011 without any understanding of how to analyze the integrity of it's construction. It appeared to be very well made, and it still does. There wasn't a rough edge to be seen. 

 
Upon first receiving it, I didn't even plug it into anything. I just wanted to see how it felt in my hands; how it played. As I played it, I noticed the E string would occasionally slip off the edge. I didn't think it was a problem with the design, but more a deficiency in my technique. I'm not a great guitarist. I silently vowed to clean up my playing style.
 
Then I plugged the guitar into my HD500 and was appalled at the heinous, digital-garble sound that was being produced along with the intended tone. It was only noticeable when I played near the middle of the neck. I posted my problems somewhere on this board (probably archived now). No one else seemed to be having the same problem, but suggestions regarding further set-up prompted me to take it to my local Guitar Center (it had already been set-up by Sweetwater where purchased). The guy at GC, who has years of experience, set it up, but failed to actually plug it in to an HD500 (they had a Pod XT family unit). Anyway, it sounded good in the store as I played it through the XT unit (string still occasionally slipping), but when I got home and plugged it in to the HD500, the heinous sound remained.
 
I related my problems to a recording engineer friend of mine. He asked me if I could detect any string buzz at all. I didn't think there was, but after listening very closely, I could hear it. He said that, while buzz is not an issue on normal electrics, some DSPs don't process string buzz very well. He said if I eliminate the buzz, the problem would probably go away. So I took it to a different (veteran) guitar specialist, lent him my HD-500, and asked him to do what he had to do to eliminate the string buzz, and to then test the guitar on the HD500 unit. When I got it back, it sounded great. The action, however, was way higher than I was comfortable with. And the string slipping was worse than ever. Completely frustrated, and depleted of funds (having spent $4000 by this time), I set the guitar aside and proceeded with my current recording project using other guitars.
 
Over the past two years or more, I have only occasionally picked up the guitar. Every time I play it, I get this sick feeling in my stomach. I hadn't been on the Variax boards and wasn't aware of the fact that the slipping was a common problem and that there was a 'fix'. However, a few days ago, I picked up the guitar and actually noticed the difference between the two distances: that of the top E string and the neck, as opposed to that of the bottom E string and the neck. The bottom E has almost HALF the clearance. I also noticed that the strings do not center over the pickup magnets: they ride low. I thought that maybe it was a problem with the neck being slightly off kilter, and that if it angled upwards more, the new nut position would cause the strings to reposition more and more, the closer they got to the highest fret, finally centering the strings where the neck ends. This, I believe, is the reasoning behind the nut 'fix'. The problem with this 'fix' is that, at the nut, the strings are perfectly positioned on the neck. So, the problem can't be with the nut.
 
Then I took some measurements of the bridge, and noticed that it is not where it should be. Following the lines of the neck, the bridge is positioned about 1/16" lower than it should be. The pick-ups are in-line, but the bridge is not. Additionally, the bridge angles slightly; it isn't parallel to the frets (not as big of an issue, as the intonation can be adjusted to correct this).
 
So, in my opinion, the problem with the design JTV-69 is that the holes for the bridge were drilled in the wrong place. 
 
Any suggestions on how to proceed?

jackoloki,

 

If there is Hi-E slipping, that can be fixed. Call the Line 6 Support

Line so they can give you options on how to proceed.

Hi psarkissian,

 

What is the fix for the E string slipping off the fret-board?  I have a JTV-89 and have complained about this since I got the guitar. It's not the hi-E it's the low-E string that falls off the fret-board.  I was going to try a different nut or even a new neck but if there is a fix please let me/us know.

FrozenOzone,

 

For an 89/89F, have a tech check and re-align the neck. Nut position can

also be a factor. That's part of my standard check list when I do a set-up.

Yours might need a slight dial-in since I worked on it last.

 

The reason for the Hi-E slip thing on the 69 is usually for a different reason.

I'm going to try to get a JTV 69s in the future and I've read a review that the problem was on there too for a customer.

 

Obviously when you're bending the notes you want to bend the strings away from closest edge of the neck, but this sounds like it happens regardless of bending.

For a minute there, I lost myself.

I hear about this off and on from those who do string pulls or Gulf Coast Chicken Scratch Blues.

The only time it happens to me on my 69, is when my playing technique isn't up to par at that moment.

Back when I bought my 69S from Sweetwater, I looked very closely at the pix of the actual guitars.  Some of them you could see that the strings were not centered on the neck correctly.  I picked one that looked good and I have had no problems.

Thanks for the response.  I will check it out and see if the neck is off a little bit and make adjustments as needed. As for the nut, I am not comfortable in making any adjustments since it lies on the fret-board in a weird way.  I think I still have a month warranty left.  Should I send it in to get adjusted?

There is a general string-to-edge clearance spec that I set to, and I have the tools.

We don't usually bring them back for a set-up issue (check with the support line on

those options). But if there is something off about the neck, I'll be able to check it out.

 

I make a point of playing a variety of styles so that I cover most of the bases. From

what I recall, your 89 played nice when it was in last. 

 

Also, it is standard with me to do set-up for the climate of the end destination (ie- your locations).

If it's a smidgen off after four days of acclimatisation, take it to a local guitar tech to get that final dialing-in.
