John Lennon with stripped Epiphone Casino The Frequensator tailpiece was used on a number of models - the point being that it would lengthen either the three thickest or three thinnest strings, maximising treble and bass response. The 1961 models came equipped with the Tremotone vibrato, which was optional by 1962. Initially these had a black bakelite cover, changing to nickel and then chrome-plated brass as the decade wore on. Both were fitted with P90 pickups (single coil), again just like the ES-330. Two variants were available, the single pickup E230T, and the dual pickup E230TD. without the center maple block present in the 335 / 345 etc. Like the 330, the Casino had a completely hollow body, i.e. The Casino had no pre-Gibson equivalent, and corresponds to the Gibson ES-330 launched the previous year, having the same dimensions and construction, but with different headstock shape and (sometimes) tailpiece. The Epiphone range of the 1960s consisted of several guitars based on the pre-Gibson Stathopoulos-era guitars, and a number closely resembling the Gibson guitars of the same time all were produced in the same factory in Kalamazoo, MI, USA.
