Heat,... it can have some effect.

Remember, you have 11 year old gear, and probably hasn't been serviced in some time. So more than likely

your batteries are as old as well, as may be getting a bit spent by now. Even Li-Ion batteries need replacing

at some point.

98-034-0009 is the current part number for batteries.

Being what an early serial number it is, could be one or combination of what I listed.

... would be the closest to you.

Or a combination of both. The 500 Electric is an older product (came out around 2003).

Solder points and other connection may be getting a bit intermittent by now.

1-What are the last four digits on the battery part numbers?

Could be it's time for newer more current ones.

2-Could be an issue with the battery box.

3-Some other thing deep inside pulling down current.

More than likely #1.

Contact the Line 6 authorized service in your area, they will have more experience with these.

If it's buzzing like that, it is more than likely a grounding issue somewhere inside. Best to contact

the nearest Line 6 authorized service center in your area. Don't try to self repair it, leave it to those

who have experience with the product.

500 connects using the VDI port and VDI cable,... and will power the 69. But it can't be used as an interface for

updating the 69.

500X connects and powers thru the VDI, connects to Monkey and Workbench HD app.

Op-amp circuits in the guitar on a separate circuit board custom mod. Need someone good with op-amp circuits

who knows how to buffer and impedance match the output, so that it can drive enough signal to whatever the effects

or amp is,... without frying anything. Basically a booster circuit in the guitar.

Or do the same, only with an external booster box, and a 9V battery.

In both cases, using the 1/4" TRS output jack.

Will need a custom guitar circuit person (someone other than me) who is up on this stuff.

Supply is 9V using battery power, XPS is the same. Inside, it sets-up what is need for the analog and digital circuits. 

But it isn't just the voltage. It has to be the correct current draw as well,... and each product has a different current

draw. Best to get the correct Line 6 items for that.

Other possibility would be warbling, hence the post about pick-up height adjust.

Old strings is another.

Could be dual tone effect, when hearing both the string from the guitar and the de-tune from the amp.

Press Hi-E string at the highest fret, be sure the string distance between the magnetic pick-up pole piece

and Hi-E string is 2mm (1/16 in, 0.07874 in).

Sure.

Early 2011.

World Music, Korea.

First thing that comes to mind is the set-up, the pick-up-to-string distance.

Solder point or (not very common) problem with the pick-up itself.

Have it checked out at a Line 6 authorized service in your area.

"Regarding spare parts - I wonder if Line6 would sell to individual owners so they could perform their own work. " --- Some are available, some are not,

and are acquired through Full Compass. Self repair is not a good idea with these, unless you have lots of experience at these.

Thank you jerseyboy.

A 12 year old 59P,... I can deal with it for you. For that, log a Support ticket in your account to contact Line 6

for a return authorization. They will contact you with options.

Error code 8000900C MIDI device timed out, does not mean it is bricked.

Double check the OS of your computer with the the application. Make certain you are using the correct OS for that app.

Less about the computer,... more about the computer OS. Check the Downloads page on this site for OS compatibility.

The 500 Electric will connect to original Workbench, but not Workbench HD. There is no Workbench like app for the basses.

Software issues,... not really much of an issues as much as it was tone or amplitudes. 

Support and parts are still available, for now, and so long as I'm here at Line 6, there is someone to service and repair them.

Very good.

Still available, don't know what the stock level is. Best to have an authorized service center check it out,

maybe it's just solder points or maybe it needs replacing. Best let the service center deal with it. It can be

a finicky switch if you don't know how to deal with it.

Typically, a solder point or two. Early 2012 build, so a couple of solder points on the 3-way switch

may be oxidizing after 12 years. Recommend an authorized service center in your area or log a support ticket like silverhead suggested.

Excellent.

Power tubes are matched pairs?

Could be the 12AX7 pre amp tubes are getting old as well. Old heater element in a pre amp tube can a reason.

Something else,... have it checked out by a Line 6 authorized service center in your area.

On a JTV, Standard or Shuriken? Yes. Kevin Cadogin of Third Eye Blind does that with the

5-way toggle switch on his two tone orange JTV-69.

Tyler is not involved in the set-up specs. His guitar set-ups would be slightly different as they don't use piezos

in conjunction with magnetic pick-ups.

We don't publish it because too many people keep messing it up.
