I've never heard those artifacts on a Variax, JTV or the Standard. Sounds like amp distortions, clipping and and maybe some intermittent solder points. If there was a tube amp in the signal chain, I'd recommend taking it in for servicing and a tube swap out.

How long since the tubes were changed out? Not something to mess with yourself, the shock hazard is too great. You will need the correct fuse, tubes and bias voltages. Best to be left to a factory authorized technician in your area, who knows the product and has access to service info and me.

So I've read. There's always tomorrow. :)

If stolen, get the new Home Secretary and MI5 to deal with the thugs. Dream Rig like that deserves nothing less. :)

"I have a first year JTV with the high e fall off, model switch issue and older firmware. Debating about updating to the HD version and seeing if maybe that plays nicer with the helix."--- As reasons go, it's a possibility, it would explain certain mis-triggering on some of what you are doing.

I have two 59's, love 'em.

The bulk resistances of the pick-ups should be between 6k-8k Ohms. Outside of that and there may be problems.

Good,... I asked because, electric guitars or tube amps are like noise antennae when it comes to florescent lights. Check that off the list then. Have to remember that with valve (tubes) amps, there's always going to be a little noise. It's just the nature of vacuum tubes.

Get away from any florescent lights that may be close by.

No problem. Wait until you hear how bad it is with Alt Tune on a JTV that needs its intonation dialed-in tighter. Warbles and it howls,... Cringe!

Check with Mark Wright at Mark Wright Music in Northampton. He used to work at Line 6, UK in Rugby, back when we had a location there. He still works on Line 6 gear. He may be more tuned-in to what's out there.

Thank you. I try. :)

"BTW: Line 6 Staff....thanks for your bread and butter answer. That's the kind of stuff that makes me mad over corporations"--- The link was just a starting point. A number of people out there are still unaware of that. Have to start somewhere, then work our way from there. It is a High Res DAC. Some else is at play in the signal chain. Being that the tone is at 15kHz, it is a multiple of the sampling frequency, so my first suspicion is that there is a loose ground point in the analog signal chain. That would allow the sample clock to fold back into the audio band. This sort of thing can occur with "mixed signal devices".

Oxidizing solder? Loose plug-in connection? Component failure in a circuit? It's more than ten years old. Maybe time for it to be serviced. Use a Line 6 authorized service center, as they will have access to service information and tools. Not something for just any guitar tech to work on.

You need the battery if you are using the 1/4" TRS connection to plug into the Helix. You don't need the battery if you use the VDI connection with the VDI cable. The Model encoder has an internal switch, you push down on to engage the Models. Some people forget that, and they think that it simply plug in and turns on, on its own. Also, check to be certain that the Helix is not controlling the JTV-69. Check the Edit Page Variax settings for that.

Older product like that, solder point will be oxidizing by now. Line 6 authorized service center that works on our guitars, with all the right tools, access to service info, and me (or my lab mate). Don't try this at home.

Good. So that's ruled out.

Check pages 21-22 regarding Variax settings and edits in the Owner's Manual Rev-D, see if that helps. http://line6.com/support/manuals/helix Sounds like something similar to the Variax Model "Force/Don't Force" edit features of our other floor effects products. Helix would have something similar.

Excellent. :) Remember the old Murphy-ism, "The shortcut is the longest distance between two points". It's like trying to drink coffee from a sieve. Mis-matched impedances are like that.

"The speaker would get Power from my TT i reckon?"--- Not through the RCA jacks. If you are going to use RCA out's for speakers, they will have to be those powered desktop types, like are used for desktop computer speakers. RCA output circuits won't drive a passive low impedance speaker, RCA in's and out's are high impedance circuits. Powered desktop speakers for computers and with RCA jacks, if you are going to do something like that.

What is it that you are trying to do?

Re-Flash the program. If that doesn't work, return it for an exchange or log a support ticket. At that point, if a re-Flash won't fix it, then it won't be something you can fix yourself.

:)

Don't do that! That circuit is not design for that. Use the proper outputs for what they are meant for. Headphone Output is meant for headphones.
