I have a 1987 G & L SB1 bass that I had the frets leveled. Well now it is unplayable. I am going to bring it to a master luthier for him to look at. I talked to him on the phone and told him what the problem was and I thought I needed new frets. He told he wanted to look at it first to make that decision. Just thought I would post to see what you guys think. It might just need a good setup. The problem is that I need pretty high action to avoid fret buzz - about 1/4 inch off the frets. When I do that, I have to press the string so much, I get fret clack. When I lower the strings so it is playable, I have so much string buzz, even at the first fret and also when I am at the 12th fret, the strings hit all the frets after that. I have tried a straight neck & relief and nothing works. When I look at the neck from the side, it looks a little back bowed. But when I look down the neck, I have a little relief. I am stumped.
