Gibson redesigned the Kalamazoo KB bass and KG guitars in late 1966 to the increasingly popular SG body style. The headstock shape was also slightly rounded off, but all hardware/components are unchanged. Functionally they are exactly the same, and the SG shape seems to have been more popular. Compare this to the earlier Mustang-style KB bass.
These are great basses, often overlooked, except by vintage guitar collectors. True they don't have a highly polished hardwood body of a 'real' Gibson but they do have much of the tone, and a lot of the looks. The power of the Gibson EB humbucker is still there, and the neck is very comfortable. You feel like you are playing a Gibson EB-O of the same era. Gibson quality construction, and components make for a very playable bass.
The basses were shipped in moderate numbers in 1967; Glacier White instruments made up less than a quarter of that years total (see Kalamazoo KB bass shipping stats). This bass is one of 501 white KB basses shipped that year.
The neck/fretboard were of Gibsons usual quality on these basses. The truss rod is the same as any Gibson, adjustable at the headstock end of the neck, requiring a 5/16" hex spanner to adjust.
It is interesting to note the internal body cavity contain impressions for four pots and a switch (aswell as the humbucker).
