A mystery issue, high pitch frequency
I just recently bought a Reverend guitar and I love it, it's amazing. However, I have a very annoying issue that I cannot seem to track down the cause of. On only the high E string, open and every fret, and mostly noticeable in the middle position and neck, there is a very high pitch frequency that is only avoidable if I very lightly pick the string. I am going to make a list of things I've tried to rule out possible questions:
I set up the guitar. Intonation, string height adjustment, neck relief, 10-46 strings like from the factory (Elixirs). No major buzzing issues anywhere, no dead frets, strings ring out with good sustain. Trem is floating as it should be.
I have dampened the springs for the trem.
I have adjusted the string higher and lower with no change.
I have checked the bridge saddle and notice nothing unusual. Same with the nut.
I have adjusted pickup height lower and higher, no significant change.
So I'm not sure where to go from here, it's really really odd and not something I have experienced on my other guitars. I am attaching an audio example. You should be able to tell how much louder and shriller it is than the other notes. It didn't pick up on the phone as well as I'd like, but it hopefully gives you an idea, it's the high note in the riff I'm playing.
Thanks for any help.
