Yeah, the glue is handy and helpful.

At this point I tend to concur with jandrio,... some sort of communications hicup. Sounds like a 'one-off" so far. Maybe the knob wasn't square on the detent point. I've had that happen a couple times. But then I've serviced a lot of JTV's.

"I have serial number 2 of the Korean production '69 (it is black). Last I heard, #1 (red) was kept at Line 6"---- Being that I work at Line 6, I walk by serial #1 every now and again. Yeah, it's red.

Don't know if that's a good comparison, since ice9mike has a number of modifications to his 89F. Not a stock unit anymore.

Hmmm.

I service JTV's all day at Line 6 in California, haven't come across this issue yet myself. And I've serviced hundreds of them. Two things here I see that are different,.... 1) I mostly finger pick, not flat-pick when I play these. 2) I usually don't play through an HD500 or HD500X. To isolate the issue down to the guitar, have to play just the guitar. Play with finger and with flat-pick. Use a variety of stiff and flexi flat-picks, those also affect such things as pluck transients. Each effect in a 500 or 500X has gain and some form of EQ or filtering,.... got to keep track of that or it gets out of hand quickly if you have a number of them cascaded together in a chain. Happens to me all the time when I tests this stuff. Sometimes it's just a matter of dialing something down on the effects board. And if you're in "Spank" model,... it's Modeled after a 1959 Strat, not some 1990's re-issue. All the Gulf Coast Blues players covet that 6th string sound. It's part of that vintage '59 Strat thing they all love. The guy who wrote the firmware tells me that, that '59 Strat was one sweet vintage blues guitar. I'm more of a Gibson, Gretsch, Rickenbacker kind of guy myself. But I go to the Spank when I want to do some David Gilmore or Joe Walsh riffs.

Limited release apparently. I enjoy servicing and working on the few that come my way. And I love how they play.

The cable you are using to connect to the HD500X is a regular CAT5 cable or a Line 6 VDI cable for Variax/JTV with the shroud connector?

The video seems pretty good as a general reference that can be applied to the power jack, just make sure that the iron isn't so hot that you lift pads or traces. You bought it used, so warranty isn't an issue at this point. Not sure where the nearest authorised service center is, but Line 6 in the UK is in Rugby. My mates there know their stuff. The other upside about going that route is that my mates in Rugby can go through it all and make sure everything is good and go through all the checks needed. Also, you check with the guys in Rugby, see if they can point you to authorised service center in your area. If you end up doing it yourself, just remember, it might be an easy solder job, but it's the easy ones that are easy to make mistakes on. I've been doing this decades, it's the easy ones that get you. Happy hunting.

OT? Not a problem. As far as I know, both 89 and 89F are still available. They both show up on our website, unless they're just not available there where you're at. Have you tried the guitar shops on Denmark St in London? Macari's, Westside, Rose Morris and London Pro Audio Centre might be a place to start. Or check Line 6 dealer listings for your area. I have a black 69, Cherry and Tobacco 59's. They're great. I know what you mean about the fixed bridge thing, the 69 is the only guitar I have (of all my guitars) with a tremolo on it. When I pick up my black 69, I think of that photo of David Gilmore with his black NOS Fender Strat, then I go into playing some Floyd tunes. Have had any of the problems mentioned here, but then, I plug in direct to the board or go through my older aged POD's prior to the HD500 and 500X.

Being the JTV tech at Line 6, here in the US,... not as much of a nightmare as you might think. I like working on JTV's. And I do like a challenge.

Take it to a Line 6 authorized Service Center in your area. There may be more to it than just a power jack. They will have the tools, anti-static station and access to schematics. And if something else is already failed inside, they'll be able to deal with that too. "Judge your skills before you tackle this"--- most definitely.

It touches the strings, from the neck through the body,... whether acoustic, electric or an active circuit guitar like a JTV, the whole of the guitar resonates and is part of the acoustical aspect of the signal. Thanks to that Greek fellow Pythagoras we have string instruments.

It was the locking nut. The bridge was okay. Odd vibrations getting processed with the rest of the audio.

That one on the end, the one that got the worn marks on it.

diggerbarnz--- If you're getting slippage, it may be the way the frets were dressed. Taking it in to an Line 6 authorized service center to have the nut shifted or a new nut installed could solve that. A neck swap would be another solution. If it becomes a problem, take it in while it's still under warranty. I have an earlier 69, and the only time I get slippage is when my technique is sloppy. But then, I don't do too many of those blues string pulls either. Most of the people I hear from about this are those who do the bluesy "string pulls" or "chicken scratch" pulls on the earlier 69 necks.

"Have the neck issues been fixed (I would hope so by now)?"---- Yes! That issue has long since been resolved. It involved earlier units and had to do with the way the frets were dressed. Newer units don't have that issue. Though I do get the random one in for servicing that need a little extra TLC from me regarding fret dressing. Enjoy playing the 69's,... I do.

When changing string gauges, make sure your local guitar tech (preferably a Line 6 authorized service center) to check and adjust the set-up (relief, action, intonation and such) afterwards. When changing gauges, the string tension also changes, and that will have an affect on the set-up. It's like that with any guitar.

Ah, those,.... heard about those, seen them around a bit. Thanks for the reminder, forgot about those.

Just be sure that it lines up with the fret board edge correctly or it may throw off the scaling. Because if that happens, intonation will be pain in the derriere (if possible at all at that point). I see that all to often, so use caution on that one.

Thanks. The techs there and I are good mates, and they know their stuff. I'm in contact with them on a regular basis. We trade notes and such. They're pretty good.

Open a support ticket to get a return authorization process going, so you can get it to your local authorized service center. There is one of three or four things that it could be. Pretty straight forward, but it needs to be dealt with from the inside of the amp by an authorized service center in your area.

If we do have one here, I'll be the one who'll check it and if needed, level and dress it. We'll see what there is here. Found one for someone a couple weeks ago. It wasn't in a handy spot to grab. Have to search and see if there is another. 600 neck have a laminated fretboard. I don't see anything on the Warmonth site in their neck section about having any with laminated fretboards.

Opening a ticket will bring visibility here to the support group,... two heads are better than one, more heads are better than two. Oh,... and the board referred to in the repair is the board on the bridge that the piezo solders to, as opposed to the main board, which is a different part number.

Don't know off-hand. Opening a ticket means that all the support people will see it and so the right person can chime in. Out here in the forum world, it's too random. A support ticket would put you with the right people for this.
