<html> <body> <blockquote type=cite class=cite cite> I've not heard of that, (But then I don't hear very well). False beats are usually caused by the string not being seated on the bridge. If you have false beats, tap down the strings, and it should eliminate the falsies. I don't think raising pitch in one swell foop, or in small increments, is going to change that. Wim </blockquote>Hi Wim,                  Leave the string alone,  a light tap on the bridge pin with a pin punch will clear up a lot more on the unwanted noise, better yet a dab of thin CA at the back of the pin will help tighten it up. Just make sure that you have some paper towel to wick up any excess. I agree with Ron, most falsies come from loose bridge pins, followed by cupped capo bars, followed by phasing hammers.
