The Kalamazoo KB bass is another CMI-owned Gibson product to feature the famous Gibson EB bass humbucker - along with the Gibson EB0, EB1, EB2, EB3, Melody Maker bass, Epiphone Rivoli, and Newport. Have a listen to some of the clips below.
Tonally it is quite similar to many of these basses - the strength of the pickup has a tendency to overwhelm the subtleties of body/neck wood and construction, but to a keen ear, it does lack some of the richness that set-neck all mahogany basses offer, and the resonance of a semi-acoustic. Compare this bass to a 1966 Gibson EB0, played through the same amp with identical settings (and some others).
1967 Kalamazoo KB played through a 1964 Ampeg B-15N, mic'd with a Shure SM57, into a M-audio mobile pre USB interface.
Neutral amp settings: volume 3, treble 5, bass 5
