Re: Jem7V tone problems near upper frets.
Oh. Well, I never got to find a combination of pickup heights that worked, and I couldn't really determine which pickup was causing the problem, because moving ALL the pickups as far away as possible didn't help at all, but I noticed the problem was SLIGHTLY resolved when bringing the pickups closer to the strings.
I decided that, instead of fixing the tone, I'll just shred fast enough to hide the trill-noise.
Otherwise, I don't think there's anything I can do, since I can't identify the problematic pickup.
Is there something other than a pickup that can cause that?
