This is the "pro" version of a tremolo unit that replaces a standard 6-point support synchronized tremolo, enabling smooth and direct arming. The saddle shape has been updated to reduce string friction. The concept is similar to the Vega Trem, using 4 of the 6-point support screw holes to fix grooved bar-shaped studs to the body, and attaching the knife-edge bridge unit to them, creating a "blade-supported" mechanism. Sonically, like the Vega Trem, it transforms the sound into a modern, clear sound image. *For those seeking further sustain and sound definition, we recommend using the concurrently listed brass spring hanger (a heavier spring hanger). This is a new, final set as the manufacturer is out of stock and the next restock is uncertain. At less than 1/4 the price of the Vega Trem (45,000 yen), this is a great opportunity for those who want to try a recently developed tremolo system.
