We have handcrafted USA instruments since the mid 1970s. Less than thirty instruments are completed each month. These are handcrafted to order by Stuart Spector and his four employees at our famous NY workshop. NS-2, NS-4, NS-5XL and NS-6XL are USA made neck-thru basses, the flagship of our USA Neck-Thru Series. However this system does not apply to more “modern” NB serial numbers….they appear to be as follows: Starting in 2011 there will be five digits after the NB and the rule is to add (1) to the second digit from the left. If there are four digits after the NB, you would add (1) to the first digit to determine the year. On the back of the headstock you will find “NB” with digits following. Note: some early SSD Czech models may not have a serial number.Ģ001 is when our Czech model serial numbers started to indicate the year of production. Use our Czech Archived Import Model Sheet on our site & use the bass specs to determine the years of production. Our Czech serial number info is as follows :ġ993 thru 2000: serial numbers do not indicate year of production. Also there are exceptions to any rule such as serial number dating. They will not determine the exact month & day.Īdditionally the serial number process has changed over the decades at our factories & is not straight forward. At best, our import instrument serial numbers indicate year of production.
