Weird High-Pitched Doubling "Chime" on JTV-59

[JSDeininger]

Hi all,

I'm not sure if this is the correct forum for JTV problems. I've been having a bizarre issue with my JTV-59. Every once in a while when I've been playing for about a half-hour or so, I'll get a very strange, high-pitched doubling "chime" sound coming through my amp. This is especially evident in the acoustic position 5 Gibson J-200 model. It's similar to the sound made plucking the strings between the headstock nut and the tuners. 

 

It goes away when I change out the battery, but will often return during a set. I'm not sure what year this JTV-59 is, since I bought it used on eBay. I've had the guitar for about a year, and it started doing this "chime" about 2 months ago.

 

Anyone else ever have this issue?

 

Thanks,

James

I've never had it happen to me but it sure sounds like somehow the 12 string sympathetic strings are leaking through. I would be curious what Workbench HD shows. I'm not sure about the JTV's and I'm not sure I will be explaing this well but the first generation of Variax's model knob was not based on detents or positions that were on the pot. I mean you got "clicks" per say but the "clicks" were piece of metal and there were indents on the knob itself but the pot was like a volume knob. So model selection appeared to be based on the resistance of the pot. This was often never an issue but some times you had to calibrate the knob. I wonder if the JTV is the same and maybe your select knob calibration is a little off. Not sure if this makes sense. Hope this helps.
