Hi Colin,
lakland built these basses only for a short time so they are rare. its basically a 55-94/55-02 (skyline) but there are two differences: first is that the 55-76 only has one mm-pickup and no j-pickup in the neck-position and the second is that the pickup is sitting in a different position. whereas the 55-94 pickup is sitting closer to the bridge to deliver better j-sounds, the mm-pickup on the 55-76 is located in the "real" stingray position which means a little closer to the neck. it sounds different, more scooped (more snap and bottom, less mids) and much more like a true stingray. the 55-94 is close to the stingray sound, but there is a difference.
the quality of the usa-laklands is outstanding so if you like a stingray on steroids you will love the 55-76.
