A medium-large version of John Cerminaro's solo cup. All the tapers of the cup were adjusted to provide as much of the sound and characteristics of the original, in a more managable package.
Cup: Medium-deep - funnel shape - with a secondary 'V' shaped throat below the main cup.
Bore size: #5
Backbore: Medium-large size with a slight concave shape after the original.
Shank: Narrow morse #0 (American) shank.
Threads: standard Giardinelli (0.660" junction) compatible with most American makers.
