I received a new JTV69S last night. The guitar was flashed to 2.21 and I immediately rolled it back to 1.9 without even playing the guitar because that's the only firmware I like. I plugged it in, works fine without the modeling but with the modeling on the A string has no sound. I am assuming the piezo pickup is dead for that string? Should I try re-flashing the guitar?

 

If it indeed is a bad piezo, can I go to a line 6 local service center and get it replaced there or do I have to send in the guitar? If I have to send it in I'd rather not keep it but if it's something that can be fixed locally, I can keep the guitar and get it fixed.

 

Thoughts?

If it's new why not send it back to the store you got it from.  It's clearly defective.  You should not have to replace a piezo on a new guitar.

I agree, you shouldn't have to deal with piezo problems until like 5 years and up later. A bad piezo on a new guitar is ridiculous.

It may not even be a bad piezo.  It is more likely a connection problem.

 

True. When I fixed piezos on my 600, Some piezos weren't workingwhen I didn't insert the connector fully.

Had the Same issue Last Night during a Show. Switched over to the magnetics. Somehow it worked again. Could this be a Connection Problem of the Digital cable? Funny that it Always Seems to be the A String.

Best regards

How about 'guessing' the A string piezo connection is loose in the guitar?

I doubt the digital cable transfer of data would be selective for a specific string.

It works or it has noise, but on all transfers of strings as it just sends a digitally encoded analog signal of your guitar as a whole and not 6 signals for each string.

Unless you already did, check your connector settings in guitar electronics guts. If this does not do anything try to slightly bend the piezo wire while playing the string to possibly identify the weak spot.

Hi,

 

I have a Variax Standard with an intermittent 3rd string. When I move the wammy bar the string cuts in and out. Any Ideas? I do electronics for a living so could trouble shoot if required.  Any tips before I take the guitar apart? 

 

Cheers

This thread is more than 4 yrs old. You might get better exposure if you start a new thread.

 

Having said that, nothing wrong with responding here....

I suggest you open a support ticket to get an informed diagnosis of what the problem might be before (perhaps unnecessarily) taking the guitar apart. If Line 6 says it needs servicing then you can decide whether to send it in or attempt the DIY approach. Warranty considerations may apply.

Piezos rely on physical contact with the string to function. If it's only happening when using the tremolo, then it's possible that the release of string tension is causing the G string to break contact with the piezo saddle just enough to cause a momentary drop out. Also, in this particular design, the saddle's height adjustment screws need to be in contact with the bridge itself, this is the ground connection...as a result, dirt and grime under the saddle can cause intermittent drop outs too, if the ground connection is tenuous. Tremolo manipulation could easily make that worse and cause the same symptom.

bad grounding between the piezo and the saddle slot due to accumulated dirt..

 

being careful not to sever its small connected cable gently extract the piezo element from the saddle (you could use adhesive tape to grab it) and clean well both the piezo and its slot in the saddle with isopropyl alcohol or another good cleaner, possibly before reinserting the piezo rotate it 180° to provide a new side of the piezo to the string

Thanks to all who responded and the great advice. The guitar is out of warranty. so may have a look myself. I do electronics for a living. Have any of you tried the Graphtech pickups? just wondering if they are compatible with the Variax systems?

I replaced the L.R. Baggs piezos with Graphtech several years ago on a Variax 300. I found them to be a noticeable improvement - brighter and louder. However your situation is different - I can't speak to how they compare to the factory Variax Standard piezo.

Hi All,

 

Followed your advice and removed the bridge, and gently extracted the individual pickups. I sprayed some contact cleaner into the empty saddles and refitted the pickups. All is working now. The small pickups can't be turned round as the little wire enters on the one side. Hopefully this does it.

 

Thanks again for all the advice.

 

Cheers
