I'm not lying. It's just that it gets into details of modeling I'm not allowed to talk about. You're talking about effects, I'm talking about cause. It only appears to clean it up. There are things going on in the software I can't get into. The appearance of cleaning up the signal is just that, appearances. At some point, somewhere, certain artifacts and distortions will appear in the E6, A5 signals when you do the piezo line cross swap. Sorry, would love to get into the deep stuff of it all with you, but I'm simply not allowed to go any deeper into the processing than that. If it were a firmware design failure, everyone would have that problem including me with my four JTV's. (oh, and, please don't call me a liar again, it's just plain not cool, and besides,... I was a Boy Scout, we just don't do that).

"Either both strings produce some mechanical noise, and either software or electronics is cleaning up on one and not the other"---- No, that's not the reason,... nice guess. Not that kind of software. Modeling, simply models the specified instrument. "OR, both mechanical signals are fine, and either software or electronics are adding the artifacts"---- No, that's not the reason,... nice guess. Not that kind of software. Modeling, simply models the specified instrument. If it were something other than Modeling, then the afore mentioned would be valid,... good ideas though. I probably would have thought the same too, if it were a processing method other than Modeling. It simply processes what's coming from the strings.

Have the service center contact Line 6 Customer Support, so we can get a better evaluate the failure, and advise further if needed.

The fact the the piezos work, shows that the piezos work, or one would've failed during the swap test. His electronics including the piezos and circuit board were replaced, the firmware was re-loaded to the latest. If there's still a problem, then it must be elsewhere. Kwendling, I don't know about your guitar, nor have I seen the repair record yet. There may be something particular to your case that's different and/or the same as Miroslav. I'll have to look into yours further. The bridges are specific for each body style and are not interchangeable for use with other body styles.

:) The more, the merrier.

Going into which Bogner, a Bogner/Bogner or a Line 6 Bogner? Which input of the amp?

As mentioned before, switching connectors on the piezos is a blind alley that goes nowhere. in some multi-channel device, that might be a useful test. But with this device, it's not a useful test except to show that both piezos work fine. What's going into those piezos signal wise,.... Each piezo routes to a connecting point on the board specific for that string. Yes,... the piezos, the bridge, the circuit board,... all replaced, and the firmware was re-loaded to the latest version.

That is the wrong supply to use. there is an XPS made specifically for that. There is info about that and other things in the Pilot's Handbook (owners manual).

Unfortunately, Modeling is more about modeling other devices, in this case a guitar. Cleaning up artifacts is something else, or I would've suggested that long ago. And if it were the case, then all the JTV's would do that, including all of mine. So it must be something specific to this individual guitar. There was a firmware update where the palm muting was adjusted and a couple other items. Since the electronics from the piezos on down were replaced, the firmware was updated and there's still a problem,... then it must be something else. All good suggestions though.

Factory string set,... good. Nut looks okay. Tuning post retainer nuts look snug. Breaking angle between the nut and tuning posts, hard to tell, but looks okay from this angle. Action is good. Button ends and winding of the string at the bridge looks snug. E6 end looks like it's clear of the A5, so I would expect no extraneous vibrations there, might want to keep an eye on it just the same that they don't touch. The Velcro is a nice addition. Also, regarding flat picks,... soft tend to thwack on the strings, stiffs tend to ping, mediums are usually pretty good. I mostly finger-pick myself. Where does "fall away" occur in regards to neck relief? Lloyd must be before my time, Michel retired. I'll have to check who else there is to check with. There's more than kind of clang tone, more than one way to do that. Have to look further at that. With the bridge and its piezos being replaced and circuit board being replaced,.... must be something else. If it were a piezo problem, replacing piezos would fix it. If it were firmware, everyone using the firmware and I would have that problem too (with my four) JTV's,... and I don't. If it were the production series of bridge, I'd see many more of these. Interesting idea though. Something else is at play here,... just have to find it.

The "clang tone" post would be useful if all the piezos had that problem. The electronics downstream of the piezo and the piezos (ie- replacing the the bridge) have been replaced, so that possibility has been eliminated. If it were a piezo, then replacing the bridge would've fix it, wouldn't it? If it were this clang tone, all piezos on all guitars that use these piezos (ours or anyone else's) would exhibit this problem, wouldn't it? So those possibilities are eliminated. (from my prior post) Hmmm,... wave sources,... just out of curiosity, can you do photo of how the strings are tied off at the tuning posts? Also how the strings are fed thru the the nut slots. It's rare, but I want to check something. Something I've come across only a few rare occasions. And remind me again what Brand and gauge set your string are? What is the action height (in millimeters) of string E6 at fret-12? ... since we're looking at possibilities, I'd like to cross these off my list.

Since the the bridge was replaced and the problem still exists, then it's upstream from the piezos. Which goes back to my previous list of possible mechanicals involved,... In the mechanical aspects,... -Could be the strings, -if the butt end is not snug in, -or not tight at the tuning post, -breaking angle of the string from the nut to the post, -the nut slots, -fret buzz,... -any mechanical buzz will come out of the electronics as distortion (amplitude or frequency). -Pick-up height not set correctly, induces warbling, which induces a host of other related audio artifacts into the final signal. -Set up, something may need to be dialed in a smidgen. Swapping piezo wires takes you down a blind alley that goes nowhere, beyond checking a couple things that has nothing to do with the source. It just amplifies it. It's a nice test, but it just shows that it's not the piezo. If it was the piezo the problem would be gone after the bridge was replaced. Hmmm,... wave sources,... just out of curiosity, can you do photo of how the strings are tied off at the tuning posts? Also how the strings are fed thru the the nut slots.

Class-B pentode is one I use a lot too.

"And yes, I understand this is not a "solution"...it was never offered as such, but rather as a means of troubleshooting the problem"--- yes, very good. Nice troubleshooting tool, up to a point. Still, need to find the source and not the affect. And that's upstream of the piezo, not downstream. If it were the piezo, the problem would've gone away when the bridge was replaced. As for why swapping wires changes things,... that would get into inner processes I can't talk about, beyond what I've already said on the subject.

Not so crusinon2,.... the piezos go to assigned points to feed signal lines specific for that string. As I said before,... haven't solved the problem, but only masked it. Since the bridge (and the piezos along with) it were replaced, then it's not the piezos. Since the main circuit board was replaced,... then it's not that either. The wave is mechanically generated,... the electronics is just making it more noticeable. Job of Modeling is to Model an instrument, not remove mechanically generated audio artifacts injected into the signal. For that, the set-up and other mechanical aspect have to be dealt with. silverhead,... yeah, at one point I thought that possible too until the bridge (and its piezos) were replaced. Good call though, on the ball as usual. Something is getting into the wave before it hits the piezo. And the electronics is just bringing out more. Need to find the source,... not the affect.

Longitudinal wave,... or any wave for that matter, is produced mechanically. It holds to the rules of Newtonian mechanics. Firmware is not the solution, firmware is not mechanical. If the Model sounds the way it does, it's because the guitar it's modeled from sounds that way. That what Modeling is. If firmware was the solution, then everyone would have this problem on every JTV that is out there. For more on waves, for those who are curious,... "Physics of Waves" by Elmore and Heath. For those curious about Modeling,.... check out Julius Orion Smith III, CCRMA at Stanford University,... https://ccrma.stanford.edu/~jos/ ... he teaches this stuff.

The electronics have been eliminated as a source, because the electronics have been replaced, therefore something mechanical is left as the source. In the mechanical aspects,... Could be the strings, if the butt end is not snug in, or not tight at the tuning post, breaking angle of the string from the nut to the post, the nut slots, fret buzz,... any mechanical buzz will come out of the electronics as distortion (amplitude or frequency). Pick-up height not set correctly, induces warbling, which induces a host of other related audio artifacts into the final signal.

You'd think after being a Mahavishnu Orch fan for four decades that I wouldn't miss that one,... thanks. Master volume, maybe just a smidge. Your settings seem fine. Class-A Triode would run hotter than a Class-B Triode. And a Class-B Pentode runs even more efficient. If you gig regularly, the 12-18 months interval would be about right for you (unless one goes prematurely). And the power tubes have to be a matched pair.

Usage will determine how long the tubes last. Gigging musicians should change them out every 12-18 months, bedroom, living room and weekend rock stars ought to change them out every 20-24 months. Over-biasing for more crunch, shortens the tube life. Making like John McGlaughlin or Al DiMeola is better for tubes than playing like a dark master shredder king with the amp turned up to eleven. I've seen fresh tubes (at other places I've worked) last two weeks in an amp, or as long as five years (in that same amp).

E6 input needs to go to the E6 piezo or strings 5 and 6 won't process correctly. Putting E6 piezo in A5's input only masks the problem,... it doesn't solve it. But other audio artifacts may show up when you do that. That's why it only appears to work. I can't go into the processor aspects of it. And BTW,... from what I've heard in the audio clips, your playing is fine.

As I've said before,... mechanical, so it's more than likely the set-up needs adjusting somewhere. And yes, the guitar is made of wood, the hardware is made of metal, so a lot things resonate. So it all gets checked and if needed, adjusted. One thing I adjust when playing my JTV's, is my technique. Knowing how sensitive this stuff is, I make certain adjustments as to how I play the thing. To paraphrase Shakespeare,... to play is the thing, so I play the JTV thing. Tomorrow, it might be my Gibson.

Depends on the smell. Whether it smelled like plastic, glass or metal. The bias specs for the EH's has already been worked out in the designed and test process, so it's a fixed spec. As far as biasing JJ's, we have no spec for that. I would have to O-scope it with a signal and dial it in to find where the bias point for the JJ's are. Rheinhold's tube amp circuitry is not forgiving of deviations from the spec, and matching our processing to it makes it even more hybrid and even less forgiving of mods or deviations from the spec. This isn't a tube amp from the 60's or 70's,... can't get away with the same kinds of tube swapping we used to do back then. Use the specified EH's,... it's the best bet.

Phantom power is to be engaged when using condenser mics only. Do not engage phantom power when using dynamic or moving coil mics or it will damage the phantom power circuit.

There is no memory battery in the unit. Authorized service center. They can fix the freeze-up issue and check for any updates to be done to hardware and firmware.

900 is good for stereo systems. Sensitivity and power transfer of the 900 make it the wrong kind of speaker to use. The "sensitivity" or "efficiency" is usually measured in dB's. High effeiciency stereo speakers like the 900, or even the JBL 4300, 4400 series and 803 Time Aligned studio monitors are too sensitive for use as guitar or sound reinforcement. Celestions are typically used for guitar and sound reinforcement. The surround material in the JBL 900's, 4300, 4400 series and 803 Time Aligned studio monitors would tear too easily if used as guitar speakers. Most guitar (and bass) speakers use more hardy material that is strong and yet flexible enough to maintain good speaker cone excursions, and not tear the surrounds in the process. Speakers these days, in general, are made to be optimal for their specified applications and uses. There are a few that have multiple applications.
