I have a Tobias Basic 5 #2077 that I've owned about 14 years. I love this bass but ever since I've owned it, I have battled saddle rocking that causes a slapping sound. This happens mainly on the D sting and is more pronounce when I play closer to the bridge. I think that maybe the bridge is just worn and needs to be replaced. I e-mailed Mike Tobias, who was kind enough to e-mail me back. Mike said that the bridge was made by Trev Wilkinson, who has been out of business for several years. Do you have any recommendations? Thanks.
