It’s definitely subtle. It’s weird overtones that are slightly out of tune with the fundamental. If I have time I’ll make another recording because it’s definitely gotten worse since I tried to adjust the string by unstringing and restringing. It’s most audible with distortion and picking, but when I’m playing clean finger style and I go down to the E string, it just sounds a little off. Like it’s out of tune with itself ever so slightly. Basically just doesn’t sound very good compared to the other strings. Reads totally in tune on a tuner. I seem to have good bass output, so still praying there’s nothing wrong with the pickup. Chromes are in the mail, so I’ll try those in a couple days and update. Thank you for your thoughts! When I restring I will try to examine the nut as best I can.
