Westone Thunder III Bass Version 1 (1983)

Body is solid Canadian ash, with a through-body heelless neck which is a laminate of maple and walnut with a 24 fret ebony fingerboard with snowflake inlay position markers.

This bass is exactly the same as the second version of the Thunder II bass

The design changed sometime in the mid 1980s, I've seen a few like the one below which have different (Magnabass?) pickups and black hardware
