I'm having an issue with my JTV69 where the signal is clipping when I play it really hard. It's most noticeable on the 3rd and 4th strings. I noticed it when using the VDI cable and it seemed like using the 1/4" it wasn't happening. But I noticed that when the alternate tuning knob is enabled it's happening regardless of how the guitar is connected.
I've tried it into multiple sources (HD500, regular amp, Guitar Rig), and I have a JTV59 that doesn't do this. So I've isolated it to a problem with the JTV69.
So I dropped it off at the Guitar Center where I bought it, it's about 4 months old so should still be under warranty. I thought to check on Line 6's site today and noticed that Guitar Center isn't listed as a service center in my area. Their tech hasn't looked at it yet so they haven't contacted me one way or the other yet.
I just don't want it to sit there for a few weeks to be told that they don't even do service work for JTV's.
Anyway, that's a very long way to ask a short question: Does anyone know if Guitar Center can actually work on JTV's or should I have just contacted Line 6 directly?
