  1. Have you been to the downloads page on the Line 6 site to check that you have all the latest Monkey and drivers for your set-up? I had to update to a new version of Monkey about a week ago. Also, be sure you're not using a USB Hub device, go direct, it's rather particular about that sort of thing.
  2. canerakcil,... It's being looked into by techs and Customer Support people. You haven't been forgotten.
  3. Interesting Soundcloud file. Palm muting during the first segment? Ice9mike,... I await the guitar with open arms.
  4. I've listened to the sound files. They were done straight through no HD500 in the signal chain?
  5. If it's a knob problem, taking it to an authorized service center is the best bet, paper only works for a while. There is a specially cut spacer made specifically for this. It fits better and is more reliable than paper,... I see the paper one all too often, it's unreliable.
  6. Do not tamper with the piezo connections on the inside of the JTV-89F, if you mix the color sequence, there will be problems with the way the signal sounds, thus compounding your problem beyond what you already have. What happens when you run the JTV (using the battery) going to an amp, bypassing the HD500?
  7. Sounds like a sticky knob, take it to your local Line 6 authorized service center that is well versed in JTV's. Still under warranty? -There's a internal knob fix for that should a sticky knob occur, it's not always needed, or it would be part of the knob already. Too many people try to improvise it themselves and end up making things worse. That would be a service center job, they would be able to get the correct part for that. -Check the Volume and Tone controls, are they loose? If so, that would also be a service center job to re-align the controls for easy knob excursions, then tighten any retainer nuts. It's a fine adjustment sort of thing. The service center would also be able to double check the set-up for you.
  8. Yeah, the people at Sweetwater know their stuff. You look for an average adjustment point, then you dial it in for your area and climate. It's wood, it's organic, climate will have an affect on a set-up.
  9. Some ghost notes (not all) are a result of set-up (action or intonation) or fret buzz issues that get quantized, and the DSP processes that along with everything else. Fret buzz would usually be a result of truss rod relief and/or action adjustments. Whistling howls in the more resonant Models (tend to be) a result of intonation being a smidgeon off. I use those more resonant Models to help check intonation in the performance, after having done a strobe tune on it. Crosstalk is more a result sympathetic vibration from other strings getting picked up by the respective string's piezo. The terms crosstalk and sympathetic vibration do tend to get used interchangeably, and that's understandable and okay, there's only a subtle and some would say minor difference between them. Be careful Charlie, nice to know that you know your limitations. Easy for me to say, some of us techs have been doing this longer than most. One guy tried it himself, shimmed the 69 neck so much that the angle and relief resembled more of a violin or an old archtop guitar neck angle. I had to pull it all apart, re-assemble it and start the set-up again from scratch.
  10. Too often a JTV goes back to Line 6 for a problem and it turns out to be nothing more than a set-up issue that a local guitar tech can take of, because of the string gauges being changed. When changing string gauges, have your local Line 6 authorized service center do the set-up for that set of strings and your area climate.
  11. Correct,.... changing string gauges isn't a problem, it's making sure the guitar tech adjusts the set-up afterwards (for the string gauge and climate for the given location). It's like that with any guitar, JTV, 600, 300,... Gibson, Fender, electric, acoustic, violin to double bass. If you change the gauge, the set-up has to be re-done to account for the the change in string tension on the neck and body of any stringed instrument. "I've never heard of anyone being warned against changing the string gauge as far is pertains to the warranty coverage"--- it isn't a warning against changing string gauges, it's recommended to have any work done on any Line 6 product, to have it done by a Line 6 authorized service center while the warranty is in affect.
  12. What's the serial number of the JTV-69S? Have to check and see what my neck stash is like.
  13. What's the serial number of the JTV-69? I do neck swaps, I can change the pick-up covers while it's apart. The neck swap would have to be for a legitimate reason, and for another JTV-69 neck. To be more accurate regarding string changes,.... it's not that we mind string gauge changes, it's that when you change gauge, it needs to be taken to a guitar tech to have the set-up (neck relief, string action and intonation) re-adjusted for that gauge (and for the climate of your geographic area). Changing string gauge changes the string tension, and that changes the set-up.
  14. Not if you mess with the functionality of the guitar, that would void the warranty. So don't go pulling up the pick-guard assembly yourself. It may be a cosmetic thing, but it requires getting under the pick-guard. Something cosmetic like that,... check with reps on the customer support line, and see if they'll approve something like that, since it requires getting under the pick-guard. I see too many times where someone knows just enough to get themselves into trouble, then I see the results. It's like those TV ads,.... "don't try this at home".
  15. Anything that requires pulling up the pick-guard assembly should only be done by an authorized Line 6 service center that has experience with JTV's. Do not try this yourself, it's not something to be done by anyone without experience in this. This is not the usual electric guitar, it's a different beast.
  16. No worries, I'm not testy. I am sometimes in a hurry to get these responses out and though I'm good with guitars, my typing skills can use some augmenting. "That's all I meant..."--- I figured as much. Ah yes, the smiley face,... :) They thrust this upon me because I asked for it. They know how much I like working on these. There are also a number of Line 6 authorized service centers in America that are capable, so I get some help. And there's my counterparts in the UK taking care of the Euro Zone. :) I also own a 69 and two 59's. :) :)
  17. Regarding the palm mute,.... which version firmware do you have loaded in? Version 2.00 program has a routine in it for palm muting.
  18. Yes crusinon2,... I'm it. Would've thought the "US Service Technician & Moderator" was the dead giveaway. The crosstalk issue,... a combination of playing technique and/or set-up. It's usually good to have the set-up checked by a local guitar tech in your area, who is authorized Line 6, and knows JTV's. Local, because climate will affect the set-up. "I know the PCB was moved to the backside of the block, but anything else?"--- No. If there was anything else, they haven't told me yet. "Unless one really knows what they're doing, jury-rigging stuff that wasn't designed to work together is at the very least a pain in the arse"--- Right you are. Seen my share of Frankenstein'ed JTV's. Not always pretty, which is why they come across my bench in the first place.
  19. Regarding string gauge,.... If you want to use 9's, that's okay,.... but you'll need to take it to a guitar tech to have the set-up adjusted for that gauge set. When you change gauges, you change the tension, when you change the tension, the set-up is off and needs to be adjusted. That info might not be in the brochures, because it's just a common aspect of all guitars. Change anything that alters the string tension, and you alter the set-up. It's like that on all guitars, not just JTV's. Also, climate of your location also affects the set-up. When you get a guitar back from a distant shop, the set-up should be done with your location in mind, so give it a couple days or more to settle in. If it is still a little off, take it to a local guitar tech for that final dial-in.
  20. "Not sure a Line6 Service person would mess with my JTV now that I've swapped out the piezos"--- Being the JTV service guy at Line 6, yes,... I would,... but I don't know if it would be warrantied at this point. But I'd service it anyway. I'm here for when a teak goes wrong as well as the usual JTV servicing,... and unfortunately, I see plenty of those tweaks go wrong. Please tread with care, it's not our father's old hollow body archtop. A JTV is a whole other kind of beast, stroke and cuddle under the chin with care.
  21. Take it to a Line 6 authorized service center that knows the JTV's. Piezos can be a touchy thing.
  22. From what I've found, crosstalk would not be a correct terminology. The tests I've made points to sympathetic vibrations from other strings, especially if it's an open string. And that sounds thru its piezo and signal path, and gets process like everything else. Crosstalk, sympathetic vibrations, similar things the terminology tends to be used interchangeably. Hope I clarified a bit.
  23. James Tyler Variax Update Checklist http://line6.com/support/page/kb/_/guitars/james-tyler-variax-guitars/james-tyler-variax-update-checklist-r102 ... is the name and link I was given. Happy hunting. -PBS
  24. I've just been informed by our guitar/DSP person that there is a newer info document just posted, so I will remove this one, so as not to have info conflicts or redundancies. -PBS
