B1-5 S4 - Prana Resonance & Classic Resonance
Size Comparison: 1C
For many years the B1-5 rim has been the 'go-to' choice for players who prefer a conventional 1C rim size. The original 1C-equivalent B1-5 was renamed B1-5 S4 when its cup contour was improved in the mid 2000s.
The B1-5 S4 is made in the standard-weight Resonance body.
Plating & Finish:
Classic Resonance mouthpieces have a shiny, buffed 24k gold finish
Prana Resonance mouthpieces have a brushed 24k gold finish
