New bore design
The YCL-CSG features a newly improved bore design. With this bore design, we have found the sound to be warmer with a larger spectrum of tone colors and shadings. The player will also notice better flexibility and improved intonation.
New bell design
By eliminating the bell ring on this model, the tonal qualities become more enriched.
Hand-tapered undercut tone holes
Skilled artisans hand taper and undercut each tone hole for superior tone quality, even intonation and a uniformed response throughout the full range of the instrument.
Silver-plated nickel silver keys
The keys are constructed from a durable hard metal that prevents breakage and deformation that can alter the response over time. Silver-plating will enhance the feel, featuring a balanced, light, comfortable touch. Available features:
Key of A
YCL-CSGA, YCL-CSGAH
Hamilton plated keys
