The Kalamazoo KB 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 bass offer. Compare this bass to a 1966 Gibson EB0, played through the same amp with identical settings here
