The DL5CBC is the Music Man style bass replacement pickup. It fits most 5-string Music Man StingRay basses after 1992 (Note: this pickup has three separate mounting ears) and it fits some Lakland and Tobis basses.

They have far more "air" and definition at the top without sacrificing lows and low mids. They are cast in epoxy to remove unwanted feedback and microphonics.Please check the physical size of the pickups you want to replace to make sure the replacements fit properly.
