Hi, I have a schecter raiden special-5. I've had this bass for a wile now, love the fast neck, very nice black cherry finish, and it sound great. But ever since I replace the original set of strings, I've been having sustain problem on d string fret 7 to 9. I think part of has something to do with the bridge, so I've been looking for replacement bridge like hipshot or full contact, but will like one that is as "direct replacement" as possible. Maybe is something else. WHAT DO YOU THINK??????
