quite long to say, but let me explain whole thing.
I have posted about my alt tune warbling sound.
Original post: http://line6.com/support/topic/21214-alternate-tune-sounds-weird/?hl=weird
Many good people advised me to go Line6 service or go get ordinary set-up. (Sorry for annoying you people and staff)
1. First, there's no Line6 service center in my country. One official distributor exists, but they said
they don't provide service for JTV, because they don't treat JTV currently. They just can order JTV parts and replace them.
So, no way to get a test and diagnosis by authorized and experienced person. That's why I entirely rely on this forum.(So kind of you people, thank you)
2. Second, I have real buzz on my guitar. So I strongly believe it is the cause of alt-tune issue like forum's advice.
I brought my guitar to best, most well-known, skillful and kind repair shops.
I showed them alt tune sound and of course they don't know how to solve it!
-One of shops guessed it is mix of real frequency and alt frequency. So out of his ability.
-Another one said it is variax system issue so go line6. But he knew there's nowhere to get official service
I said forget about it just fix this buzz (asked normal set-up)
They commonly diagnosed that
-nut is little low on low string (6th and 5th)
-frets are uneven
-buzz can occur with low action
I asked them please replace nut or leveling fret or make action higher or do whatever to fix buzz.
But they denied because nut is not too low and whole set-up is quite ok, so nothing won't change.
I don't still understand. They caught problems but said nothing will change? I was disappointed there and got home back.
Go back to my original question about alt tune warbling,
I think it was OK first time, but after I change my set-up, it started, I guess.
Not sure for that, but if it's true, set-up is THE solution.
And in my opinion, leveling fret is the most priority to fix buzz.
Let me bring my guitar to a new rising star of repair shops.
It is getting famous, so I hope it accepts set-up.
I won't touch my guitar until then. But what if it also denies? I have no idea.
Sorry for making you guys angry and annoyed.
Thank you always.
