It's time to log a ticket with Line 6 support. Make sure your guitar is registered.

Could be the set-up, if the pick-ups are set to the wrong height too close to the strings, the magnets pull on the strings, it can sound warbly or distorted. Using Custom settings in Workbench HD, if a setting is taken too far. If a Flash update didn't quite take like it should, can sound odd. Going back to defaults can help there.

"White noise suggests a high noise floor, and that goes to gain or an impedance mismatch between devices"---- Your finger is a perfect example, it too has impedance. Input and output,... impedances must be matched between the devices being used.

Rode NT1-A is a condenser mic and so it requires phantom power, especially when using JFET and bipolar transistor circuits, or tube condensers. These components (JFET, Bipolar and Tubes) are active components and require a power source. Neumann mics, Pearlman mics and the like require a power source or phantom power. The UX1 doesn't have phantom power, but the UX2 does.

Not spam, no PTB, just good grounding practices. Check out AES journal for June 1995. Bill Whitlock is the guru. I won't bore with my curriculum vitae, it's rather lengthy. There was also a really good piece in the magazine EDN back in the day that was good. And of course there's IEEE's Spectrum, Bob Pease and his Pease Porridge and Robert Lucky's column,... that have all had some good stuff about grounding over the years. The Pensado Papers of their day, when it comes to circuits. Like I said, I get enough units back incorrectly grounded. And not just guitars (though I just got done with one an hour ago). And it's never pretty. Just trying to keep your gear from ending up on my bench.

"... has dedicated solder pads on the PCB expressly for ground return"--- You, Charlie and I know that 'cause we're circuit geeks. Not all out there are as savvy about circuits as you and I are. All grounds must be properly grouped. I get back the odd mod, now and then, that's done wrong.

It's a little deeper than that. Grounding on something like this isn't as simple as some would thing. Not the usual bill-o-fare. It's a little more complex than simple grounding. Certain things that have to be dealt with and considered for proper grounding.

What kind or brand of mic?

With the JTV, the bridge and saddle are the ground.

Yes,... that too.

59, 69, 89 and the Variax Standard all use the same one. It's the 89F that's the odd one.

Post January NAMM 2016 review issues,... several of them.

Mesa, Groove Tube, JJ's,... fine tubes. Just not in a Bogner designed amp. These are hybrid amps with both analog/digital with tube and solid state components. These are not the tube amp of the 1960's yester-years where you can swap tubes willy-nilly and have it work. These amps are very particular. Stick with the specified tubes. Those are the Sovtek 5881WXT Matched Pairs with the cup based bottom, Chinese 12AX7B is good. They are not designed to handle substitutes. I see too many come across my bench with substitutes, and incorrectly biased power stages,... so they come to me blown and not working because of it. You can't get away with the same kinds of tube substitutions we used to get away with back in the day. This is a slightly different beast. Tube substitutions,... please don't do that.

It could as simple as a half loose connector coming up on one side connecting to the main board. Or it could be a failed piezo element, which would require an authorized tech with access to service info and parts.

The XT Live is an older product, there may be some oxidize solder points by now. It should probably be checked out by your local Line 6 authorized service center who knows the product. When connecting the 700 Electric with the VDI cable, it's a good idea to remove the batteries. It doesn't like trying to run both at the same time. The signal line for the audio is different than the line used to talk to Monkey. There could be an oxidized solder point inside the guitar behind the connector. These are both older products that may require servicing. I would recommend your local Line 6 authorized service center for a thorough check out.

Have someone with experience with the product do the dismantling. An anti-static set-up will be required, digital boards in general, typically have CMOS chips on them, and are susceptible to damage from any static discharges. Keep the circuit boards in anti-static bags while your guitar is at the painter.

1) Use tools with insulated handles. 2) Do not bias JJ's to the usual SV bias voltage. Don't use JJ's. Aside from that, the video is okay. These are not like analog tube amps from the 1960's. Can't go swapping tubes out willy-nilly and go biasing to the usual voltages. There are minor variations in the characteristic curve or transfer function of the tubes between manufacturers. One bias does not fit all. Love JJ's, love Groove Tubes,... don't use them (or Mesa's) in these amps. I see way too many of these come across my repair bench for no other reason than the wrong tubes with the wrong bias. Use the specified matched sets for power tubes, and have them properly biased.

"I doubt that anyone at Line6 cares if you swap necks. Why would they? To fix the difference, you can mod the neck pocket"---- Yes. You can work the neck pocket side of it, or the neck side of it (as I sometimes do to fit a neck). Just be sure to maintain the scale length, so there won't be problems with intonation of the guitar. So for the newbies and uninitiated,.... please be aware of that.

"Imho, I think the powers that be were not too happy with so many people swapping necks on the JTVs. Doesn't surprise me that the Standard is not Strat-replacement friendly"---- Sorry to kill the myth, but,... they don't take measurements of Warmoth (or any other neck) for such a purpose. Though, it would be an interesting strategy. Maybe it's the 3rd party parts and neck people who won't make their necks and parts fit Line 6 guitars,... like they do for Fender or Gibson. Now there's a conspiracy theory for you. ;) But in all seriousness, we're like the other companies, we make our guitars to our specs, and it's up to the 3rd party parts people make their components to fit that spec (like Gibson or Fender specs),... ... and not the other way around. Yeah, I get it. After all, I'm a custom rebuild guitar tweaker myself. Been an interesting read so far. Sorry to kill the conspiracy myth.

As the frequencies gets higher, line of sight s more of a requirement. If you are playing at a venue with pillars and other obstructions, that "may" have an affect on your receiver reception.

What's the Serial number on the head-stock?

Would be good to have the whole thing, but we can deal with just the chassis. Okay.

Apparently not,... http://line6.com/support/page/kb/_/effects-controllers/fbv-mki-mkii-controllers/the-complete-line-6-pedal-compatibility-faq-r58 ... but you can double check with the list. The new FBV3 board is backwards compatible though.
