Choking frets at the octave...7vwh

[Ralph khoury]

Hey guys, i have a 2002 jemvwh, i noticed that on the octave position tapped notes dont come out loud, there have a low or no volume at all, the more i move towards the 24th fret, those frets doesnt buzz though.
however the neck have a slight curve to the inside, the opposite of a bow, just a slight curve (starting from the 12th fret towards the 1st)... could it be the reason? everything below the octave position is normal...
the action is a bit high, but i dont think its an issue cos i have another guitar with a higher action and it taps wonderfully everywhere...
what could it be?

Might wanna try loosening your truss bar... sounds like it may be too tight... and bowing your neck too much.

hey man i found the problem, it wasnt the frets, its just that i have a problem in the electronics and the pickups are running at half their power. thats why i get the feeling that the notes are chocking, since they barely make it to the amp.
