Stuart and his business partner, Alan Charney, sold their Spector Guitar company to Kramer Guitars in December 1985. Production continued at the Brooklyn workshop during the 1986 transition to the Kramer factory in Neptune NJ. The final Brooklyn era serial number was #1187, completed on July 1 1986. Alan stayed on as head of production for Spector at the Kramer facility.
I visited Stuart and Alan at the Kramer factory in Neptune, New Jersey a number of times in the late 1980s, but never with a camera. The only photo I remember taking is below, taken during my final Kramer visit in 1991 : the Kramer sign outside of the building.
NS-6 #003
​Electric Guitar
​1987
This is one of less than 200 NS-6 electric guitars made in the USA during the Spector/Kramer era. I have owned a few of these guitars, and all of these had the same pleasing "chime" to their tone. Also personally I prefer to play and maintain NS-6 guitars like this one, with a hardtail style bridge.

A tilted humbucker in the bridge position was a Kramer guitar spec in the 1980s. Rumored to be the only NS-6 made with the tilted humbucker, however I remember seeing one more guitar made with this feature.

After receiving this guitar, original owner Billy Thomas custom made the bridge pickup to fit the tilted rout, and used a Spector branded single coil for the neck position pickup.

This guitar has solid non-figured maple body wings, a pau ferro fretboard with 24 frets, gold hardware including a Schaller one piece hardtail bridge and straplocks, and a beautiful Red Stain Gloss finish.

In the Kramer production book, NS-6 #003 is properly noted as having a completion date in October 1987 and a fixed bridge, but its finish was incorrectly recorded as a Solid Black Gloss.

Purchased from the original owner, my friend Billy Thomas, the founder of the Brooklyn Woodworker's Co-Op. This was his personal guitar and as such has some expected player wear.

NS-2
​Fretboard
​1989
During one of my visits to the Kramer factory I purchased this NS-2 fretboard. Made of dark pau ferro, the common NS-2 fretboard spec during this time, this fretboard was not used to complete a bass because the inlay routs were misaligned.
NS-2
Unfinished Neck and Body Wings
​1990
During a visit to Kramer after their production has ceased, I purchased an NS-2 neck and a set of body wings. A few months later I glued the wings to the neck, routed for the pickups and a Leo Quan bridge, and sanded the body to have a little extra curve to its shape. This is how the bass remained for years.

I took this photo in 2002 when photographing my collection.

In the mid 2000's I sold this bass to a friend who completed this project bass.
NS-2o
​1989
I purchased this NS-2o from Kramer after they had shut down production.
Another photo from the vault! Dec 1991 : Setting up for a recording session (I was hired for a two song r&b demo). For the fretted bass song I used my NS-2o. I sold it not too long after this session to a friend who used it live for MANY years. (For the other song I used my Brooklyn era NS-2 fretless)
During the Spector/Kramer era of the late 1980s I continued to play my Brooklyn era NS-2 #603 live and in the studio.

Except for the NS-2A, all of the basses shown are from the Brooklyn era. Clockwise, left to right : NS-2 #712 fretless, NS-2A (my first Spector bass), NS-2 #401, NS-1 #021, SB-1 #73877 (peghead visible), NS-X #066 (I am holding this bass), NS-2 #603 (Vince is holding this bass).

Look closely to see basses in process for Geezer Butler (top right) and my good friend Ian Hill (bottom left) ! Also some EVH guitars can be spotted in the background.
The USA production for this era was as follows :

NS-2 / NS-2o : serial numbers 1188 thru 2719.
NS-5 : less than 100 were produced.
NS-6 electric guitar : less than 200 were produced.

Instruments were serialized at the start of the building process and completed out of order. Two consecutive serial numbers from this era may have been completed many months apart.
