1 heycalebmorris 1 week ago I picked up a 5191 on Reverb and have taken it to the shop twice. The tech fixed the intonation, stretched the strings a ton, didn't hear or see any jumping in the nut when tuning, checked the bracing and the bridge but it's still going sharp, particularly on the low E, D, G and B and then flat when it's not going sharp. Each way about 2-4 cents. You maybe get 20 seconds of playing before it goes out again. Any ideas on what else it could be? I took pictures of the nut bridge and tuners but the forum is only letting me post one. Oh and the strings are wrapped 3 times max. Thanks for any help you can give!
