Hi, I recently got a Hohner B-bass from ebay, and I have a couple of problems. One is that I like really low action, but I have to increase the string height more than I would like to avoid fret buzzing. If I were to put a new nut with the slots slightly higher than the existing ones will that help? The other is that one of the frets is loose in one edge, would a quick squirt of superglue be enough?? Thanks!
