Does it sound like a fax machine over a phone line, or a whistling kind of whine?

Thanks, I remember this audio file. Hear what you mean, definitely odd. I'll have to see if I can reproduce it here.

Are these older patches saved from v1.71 to v1.90 from Workbench? There may be a patch format compatibility glitch. I'm told that a patch or two might have distortion from that. Haven't had one come across my bench yet. If it's Howling and whistling, the JTV probably needs it's intonation dialed in closer. If it's a warbling sort of buzz, the magnetic pick-up height may need adjusting. The Magnetic field can pull on the string causing buzz and warbly distortions. -psarkissian

Things to consider with fret buzz--- Set-up,... neck relief and string action are things that relate to fret buzz. Need a guitar tech for that. Also,... have him check the nut slots at the headstock, and make sure the slots have been de-burred, a burr in a slot will give the same sound like fret buzz. I see that all too often, and mistaken for fret buzz. Have the guitar tech check the retainer nuts on the tuning machines, that they're properly snug. Don't do this yourself, have a tech do it, over torquing is bad. As well as all the mechanicals from tail piece to tuning machines.

True,... with the more resonant Models and Alt Tunings,... good technique and good execution is part of it. Nice thing about some of these Models is that they don't let me getaway with anything. Especially with these delay and reverb patches on the X3 Live at my bench. It forces me to not be sloppy with my technique and execution, or I'll hear it in a big way.

Fret buzz is a sign of a set-up adjustment such as relief or string action. And Don,... I see in the support ticket that Hugo is on the case,... good. We'll get it figured out.

I thought it might be an HD500,... I was wondering why the wave-file sounded like there was a little digital clipping,... -Check the Input Impedance Selector on the Edit Page, select a less noisy Impedance Setting. - Check your Volume Pedal settings in the patches you're using, bring them down to about 70-80%, then bring up gradual until you hear some audio break-up, then dial it back a smidgeon. I've come across this a few times, just a matter of monitoring the signal path amplitude levels. There are a few places where over-driving or clipping a signal in HD500 can be done, so monitor your level throughout the signal path.

Don't know if it's a design problem,.... I haven't seen this problem before in all the units I've serviced, and that's quite a few. That's why I was asking about the set-up, rule that out first. Four a in a row verses all the units out, is outside statistical possibilities. With all the units, donmr is the common one here. Could be a number of things, now it's a matter of narrowing it down. ***Also,... have you done any updates of the Flash using Monkey? If so, are you using the JTV Interface to do that? And I tend to stick to stock gauges of strings, 10 to 46. If you change the gauge when you change the strings, you'll need to have the set-up of the guitar checked and (if needed) adjusted by your local guitar tech.

Hello donmr, Four of them,... Hi, I'm the JTV tech at Line 6,.... - What are you playing the JTV-69 through? - Using the 1/4" TRS output using the Battery, or the RJ45 Variax output? - If you're using the Variax output, what device are you sending it through? - Specifically which Models are doing this? - Which Alt Tune setting (if any) are you using when this happens? - Have you done any updates of the Flash using Monkey? If so, are you using the JTV Interface to do that? Are you bringing over older saved Models through Workbench, after an update? -If you change the gauge when you change the strings, you'll need to have the set-up of the guitar checked and (if needed) adjusted by your local guitar tech. This will allow me or my colleagues to reproduce the conditions to better narrow all this down. Thanks.

I don't worry about how close or how far off the Models are from the real ones that I own,.... they're close enough for me. A guitar that does makes the sounds that it does, what these do, they way they do it (and I own a 69 and two 59's),.... it's bloody marvelous! Okay, so I'm a little biased because I'm the JTV tech here at Line 6, and I own three JTV's. They feel good, play good, and when I get done servicing one I get to test play them. It's hard to stop playing them. And this new Workbench HD has some cool features to boot. It's easy to get wrapped up in the minutia of it all. In the end,... it's all about the playing! -P.B.

Al--- Did you use the update document circulating around? The posting "Try This" and Johnnyayy's and a couple of Doc Rock's postings have good tips. Had one JTV the other day, that after update, it took two more "re-install" tries before it locked in the firmware and got an "update successful" message on the screen. drdamski--- With the 1/4" plug to engage the battery, try a Tip-Ring-Sleeve type,... if you aren't already.

There are two kinds of whistling sounds,.... -Whistling howl from a clash of harmonics. For that, have the intonation checked and dialed in in smidge tighter. A guitar tech should have a precision tuner like a Peterson for that. -Whistling that sounds like a high frequency fax transmission would point to an update error of some kind. Try updating or re-installing the Firmware. P.B. Sarkissian

pwik, What's your computer platform? What's your computer's Operating System that you are using? -P.B. Sarkissian

Buzzing and other artifacts do similar, but not the same. Buzzing is typically from the action set low at the bridge, or relief too straight and flat. Other artifacts can occur from intonation, where it may need to be dialed in a little closer by a guitar tech with a precision tuner. The $30 Samsons are good for quick tuning of a guitar, a Peterson (for example) is precise enough for doing intonations (which is what I use for tuning and intonations). -P.B. Sarkissian

jefflynyrd, "Warble" is usually a sign that the pick-up height needs adjusting, the magnetic field is pulling on the string and affecting the signal. -psarkissian

1/4" plug is in, okay. The Battery is in too? Green LED's on both ends of the JTV interface box? Having the 1/4" plug into the jack engages the battery. If the volt should sag or the data gets interrupted, then the update won't complete. Engaging the battery helps keep the line up as added insurance. And registering the serial number is a good start,... easy thing to overlook. -P.B. Sarkissian

The "Spank" on my JTV-69 test fixture sounds fine here at Line 6. There is a certain clarity and spectral consistency between that and the guitars they are Modeled from. No mid-mud in the EQ on certain models. Sounds like my music partner's Strat. Ricki 12-string, acoustic 12-string and the ES-335 all sound very close to the real ones I own (Ricki 370-12, FG-230 acoustic 12, ES-330). Newer version, newer models, newer sound. Sure, it'll sound a little different. -Partev

Chuckewheat, Are you able to connect to Monkey and "roll back" the Flash to v1.82? (do not use v1.82b) Then attempt an update from there to v1.90 according to the "... Try This" document. Then, again from v1.90 to v2.00 Flash. Might want to do it incrementally. -Partev

Yes,... leave it in magnetic mode, and volume down is a good idea (though that's not been in problem in my experience). Do it as added extra insurance that, that aspect of it won't be a problem. But, do not mess with the cables, connections or controls while updating anything. -Partev

Once updated--- Unplug, then plugin to re-initialize the board,.... "Change Device" to refresh the GUI on Monkey,.... "Keep Existing Patches"--- say NO! "Re-install" v2.00 to re-assure that no update translation errors are in the update. I know the document says v1.90, the document was create in June. Now that v2.00 is out, I'll be updating the update document. Until then, pretend that the document says v2.00, instead of v1.90 Flash. -Partev

The guitar/DSP person here at Line 6 informs me there is newer info posted and that this PDF that I posted here is now out-of-date, so it will be removed to avoid confusion and redundancy. -P.B. Sarkissian

I have three JTV's of my own--- a Black 69, the second unit I did the Tremolo Mod to, a Tobacco 59 and a Cherry Sun 59,... yeah they're great. JTV-59's,.... Sweet! Luv 'em. Then there's yours with the Bigsby on it, double sweet. If we petition to make it a regular production thing, I'll have to service them,.... hmmm, yeah, I guess I can deal with that,.... just hope our guy in parts procurement can. -P.B. Sarkissian

3-Way Toggle,... that's the one. Thanks, it was a sweet ride playing that one. Everyone here in Customer Support was a bit wow'd by it. Now I have to make a point of being at What's Next. I'll try to make it. -P.B. Sarkissian

Is that the same one sent to me at Line 6 recently for some serving? P.B.Sarkissian

Check out the entry on this forum page for,.... Problem Upgrading To Ver 1.9 At the bottom of the posting,... I'm the JTV Tech here at Line 6, I posted a link for a procedure document I created, that we use here at Line 6 for updating Flash. No, didn't brick it just yet,.... Double check your set-up and hook-ups to and from computer, any MIDI, the JTV interface box and whatever else you have hooked in. Then try using the procedure in the link, and if needed,... run it twice. If that doesn't work, then you may have brick the Main Board. A local authorized Line 6 service center would be able to deal with that. -P.B. Sarkissian
