Im thinking it may be from the 81 sitting too high. Ive only had it for couple of weeks and its first time with active pups. All of the harmonics ring out thru 60, but when I select both pups they dont. Too be even more specific, the 4th fret on top two strings and 9th frets on bottom two are the open harmonics that are completely un-audible.
I dont have a digital tuner, so Im not completely sure, but the intonation seems fine.
I hate messing with sh!!, bc it becomes a never-ending process for me, lol. I'll drop the pup and see what happens.
