You’re looking at a member of the new 1 Series Old World. We decided to incorporate the Old Worlds under the 1 Series umbrella because the general construction is the same - the differences lay in there being greater tension on the bow of the Old Worlds to mimic the firm feel and exceptional stick definition that results from bronze that has age hardened over several decades. Additionally, the height of the lathing grooves has been reduced as is the case on cymbals that have been played and handled for many, many years. Lastly, a mellow vintage patina rounds out the Old World package. There is absolutely no need to spend thousands of dollars on an old vintage K anymore. This prototype has a clean lathed outer edge top and bottom.
