I've never had to tamper with my basses before - I've pretty much just owned and played! However, my Geddy Lee bass has developed a problem. When I play the first fret on the G string, the string has started to buzz really badly. For some reason, the string when pressed on that fret now seems to touch other frets on the neck, creating a buzz/muffle. I've done some research, and I believe I'm correct that the bridge needs a small tweak with an allen key to raise the string slightly? Is this a specialist tool? The Fender allen key doesn't fit, as the Ged comes with the Badass bridge. I always use 40-100 D'addario EXL 170's, Nickel. Are these the wrong gauge for the Ged? Should I be using a 105 E, or would this not make any difference? The bass has a lovely low action, but this problem has just developed. I've had the guitar since about June, and it has had plenty of gigging. I'm in the UK, so it hasn't had massive temperature changes. I got a bit worried, as none of other guitars ever needed this. The neck is totally straight, so no problems there. Any help or advice much appreciated...or any other Geddy owners wih similar problems?
