One thing that is considered in a set-up is the climate of the geographical location of the end destination. Climate will have an affect on neck relief. When a JTV is serviced at Line 6, the climate end destination is considered. The set-up is done to specs, then adjusted for the end destination climate. Sometimes the climate changes during shipping can have an affect. Wait 2-4 days for it to settle-in after arrival. If it's a little out of adjustment, take it to your local Line 6 service center and have it dialed in for the last fine adjustment, that last fine tweak. Also, remember that if you change the string gauges, that will change the tension and that would require and adjustment in the set-up. It's like that with most guitars, not just Line 6 guitars. And with acoustic instruments (guitars, violins and such), climate change is even more critical, and has more affect on the instrument.

Since it can affect function,... best bet is to take it to an authorized Line 6 service center in your area and have them do it, that knows the specs and has access to the service info. That way there won't be any questions about warranty. I see too many of these come across my bench because someone went to an outside tech, who set it up to Fender specs (on the 69) or Gibson specs (on the 59), it didn't work, then the tech got in over head,.... then it ends up on my bench. Save yourself time and trouble, use the Line 6 authorized service center that knows JTV's. They can point you to one on the Customer Support line or the Customer Support ticketing system, through your account page.

The "S" version 69's have a slight different neck and fret dress spec than the earlier 69's prior to the "S" version. High-E slip was never an issue with those, It was just a very small batch of early regular 69's. Was never an issue with the 69S. Have the set-up double checked by a tech,... who knows the specs for a JTV.

What is the serial number of your guitar? Have you logged a ticket in the ticketing system through your account?

JTV guitars are strung with D'Addario XL-110 (10 to 46 gauge) from the factory. When you change the gauge, you change the tension, when you change the tension, you change the set-up. When changing gauges, be sure to have the guitar re-set up by a guitar tech for that gauge set.

Have the set-up checked (by a Line 6 authorized tech). Sounds like the action is a smidgeon off on that half of the neck. The more resonant Models can exaggerate such things. Going from one location climate to another can have an affect on the set-up.

String action overall is adjusted at the bridge post, the piezo saddle allows for dialing-in an individual string. Altitude can have a little affect, but it has to do with the climate in your area, mostly the long term temperature and humidity. Amount of Neck Relief in a set-up is set different for a guitar in a temperate zone than for a guitar in say, the Great Lakes region. Neck relief and action sets the string level and done right will prevent fret-to-string buzz. Changing string gauges requires adjustments in the set-up, because changing gauges changes the string tension, so a whole new set-up is required to adjust for that. And what ever you do, take it to a guitar tech who knows how to do this correctly and knows the specs and range of specs.

So "chuckewheat", the 59 isn't working? Have you filed a ticket or requested an RMA for return?

"zaphodboy", btw, I have have three JTV's, never had a problem with any of them.

Are you using a TRS plug for the 1/4-inch jack? It prefers TRS to a regular guitar plug (TS).

On a 69, you should only need to adjust the individual piezo. Adjusting the bridge posts needlessly changes the overall action on all the strings, when you need to do only one. Make sure of the relief and at what fret the fall-away or leveling out occurs. Check the intonation with a precision strobe tune (not one of those $30 ones from the corner music store), or have a local guitar tech do intonation on it.

Just the neck is US. If I recall,... it was a Beta unit, and some stuff done to it by Tyler himself. So it's not totally factory, it has a minor alteration or two. I enjoyed working on it recently. Plays nice.

A set string set with 10's is standard. Relief fall away, around fret-9 is good. Action at 2.0mm, except for B and Hi-E at 1.8mm, for action height.

Yes, it is a Beta. No, it's mostly the lighting. It is slightly darker, but not by much, not as dark as it looks in the video. It's a standard Lake Placid Blue,... from an early run. Just got done servicing it a week ago, or so. It does play real nice.

That has to be dealt with on the inside by a tech, it's not something for a user to do. Find the nearest Line 6 authorized service center in your area. They will have the right service info, proper tools and access to what's needed. I've come across this once or twice before, it should be save-able.

Try it with a TRS cable, instead of a regular TS cable. It like to see TRS,... Tip = signal Ring = DC-Volts Sleeve = signal return

There's two really good techs at our Rugby location. I'm in touch with them constantly about guitars. They're pretty good. Among the few people I would trust (besides myself) to work on my three JTV's,... if only I lived in the UK, that "green and pleasant land". Be careful if you decide to go into it yourself. It's not our gaffa's Gibson archtop or vintage '59 Strat. It's a different kind of cat, need to cuddle it under the chin differently, or it'll bite. Luck,...

Also, there maybe warranty implications should you do it yourself. Would hate for you to break the warranty. That would suck should you need to have it serviced later. And I've serviced hundreds of these (literally speaking).

Take it to an authorized service center. This is not some old electric guitar with passive electronics. One wrong move and it will be bad, then it ends up on my bench. If you don't already know your way around the insides of this, then it should be left to someone who has experience with this guitar. There are static sensitive components in there. Pulling the pick-guard assembly on a 69-type guitar is not to be taken lightly.

Are you using the VDI connection or 1/4" guitar plug and battery? If you're using 1/4" guitar in (with battery), is it a TS (1 insulator ring) or TRS (2 insulators rings)?

Sounds like you got it into some sort of "save mode" or held down one of the knobs too long and it went into some sort of mode. If need be, and you want to get into a factory default set of settings, the re-Flash the unit using Monkey. Otherwise, your probably fine. I've serviced hundreds of these and the only time I see LED's light up in other than the usual colors, is when it's in some programming or save mode. Which is something I never need to use, since I use it as is and don't do much custom stuff. Sounds like you're okay now. Contact Line 6 support if that should change.

With neck relief, it takes about two days for the wood to settle into its position. It's not like action or intonation, where the results are immediate.

Buzzing above the 12th fret, action low, a sign of relief is over-bowing a smidge, that goes to how the set-up is. Sounds like a set-up needs to be done from scratch first, then go from there.

There are a number of things that can contribute to warbling, RealZap mentioned pick-up height. Yes, I see this often enough. The sound sample is more indicative of string buzz (not warbling) from the string nut slots, if there are burrs or wearing in the slots. Fret buzz can also contribute. Both kinds of buzz can become part of the signal and end up being processed like the rest of it, hence this distorted dual-tone effect from being Alt Tuned with the main signal. Intonation can be off enough to where a dual-tone appears. On a couple of occasions, an 89F turn out to have the piezo lines in the wrong sequence. An easy fix at the service center. Typically, it's a matter of which string and how it manifests. It won't always be the same every time, in every situation. It requires a service tech experienced with this product to tease that out. Is on all the strings or just a couple? Every fret,... or just certain strings on certain frets? Trying to do it yourself can leave you chasing your tail or chasing ghosts in the machine. It's not our grandfather's arch-top Gibson anymore, with passive electronics. Need a service tech (Line 6 authorized service) experienced with troubleshooting this product for that one.

"But the neck, if it were not for the hole spacing, would be a drop-in replacement. Any half-way sentient luthier...if they succeed in making a living wrenching on guitars, should be able to handle it without too much drama"--- Most definitely. :)
