When I try to intonate the strings the indication needle on my tuner jumps around so much that it makes finding a steady and accurate reading very difficult. The problem has even more presence in the B and E strings. I use D'addario Slowounds but I've replaced the B string with a Ernie B because the Ernie sounds better to me. I've tried DM2000s but I don't understand how people like JT use those exposed core strings because they sound, to me, sooo incredibly weak. I know to tune the 12th fret harmonic to the 12th fret note and adjust the saddles n such. Unstable reading or not, I've gotten the intonation as close as I can but the 24th fret is always too sharp. Can someone tell me what causes this, and/or how to fix it? As always, any feedback is greatly apprieciated and needed. Yes I'm very aware how disorganized and nonlogical this post is. And i've just realized that this is in the wrong forum. please move to "SETUP"
