Spector have been around since 1976. Originally made in Brooklyn, New York they were later bought out by Kramer in the mid 80's. Stuart Spector eventually bought his company back and now make fantastic basses at every price point - from entry level Korean models through fantastic professional level Czech models to the American custom shop models.
Their key basses are the US NS2 (an industry standard) and the EuroLX models, but their are many others including ReBops, Fortes etc....
Warwick licensed the NS2 design from Ned Steinberger/Stuart Spector in the mid 80's and then basically kept the design (only amending it very slightly) without paying the relevant royalties as the years went by. Thieving b*stards...
Spectors are a different animal to Warwick in every way though. Original is best....
