For about 6 months I have been noticing a noise when I played my JTV into my HD500 and then directly in my church PA system using the XLR out. It was occuring when I strummed pretty hard (I do that a lot). When I first noticed it we had just installed a new digital mixer. I thought for sure that I was simply overloading my channel input on the board. Nope. Tried reducing input. Didn't go away. Next I blamed the HD500 thinking the VDI input was simply too hot for it. The problem did not occur when using the 1/4" input. I never knew that because I always use the VDI connection on stage so I can store guitar models in patches. I still wanted to use the VDI connection so I started experimenting and found that the problem came down completely to the 3rd string (G). I opened Workbench HD and lowered every string volume down as far as it would go and then one by one listened to a highly amped signal of each string while strumming like I play on Sunday mornings in worship. The noise only occured on the G string. Lowered it's volume by 6db and the noise is gone. In my opinion the lowered G string volume does not seem to bother the sound of the chords and notes I play. Not enough in my environment to make a negative difference.
So, for all those of you who have also searched for that noise that resembles a banjo attack when playing JTV models that aren't a banjo, I encourage you to try each string alone. When I finally did that, the problem was TOTALLY obvious.
Now, does anyone know if it is possible to change the piezo on just the 3rd string or how do I go about getting it so that 3rd string doesn't quack when strummed hard? I am happy with my current solution but wondering. I noticed the piezos on the Line 6 store don't work on the JTV.
