I just picked up a MIM fender jazz the other day... but there is a problem with the bridge... When I play hard on the E string I get horrible electric metal scratching sound... like if you were to plug your bass in after your amp is on... like that electric metal sound... I've changed the strings to the ones I prefer but nothing.. I changed the setup... raised the action, but it still happens, just not as much... I'm not sure what's wrong... any suggestions??? I'd prefer to fix this problem over buying a new bridge... help please..
