Westone Thunder 1-A - Black

Westone produced guitars and basses out of Japan in the 1970s and 1980s and more recently in England. 

The Westone Rail Bass was a product of the experimentation with new composite materials and headstock-less designs in the 1980s. It featured a pickup that was slide-adjustable on two rails, so that the pickup could be intentionally placed at a certain location to get a specific tone.
