The Japanese art of Urushi is a tradition dating back 10,000 years. This natural lacquer is sourced from the caustic sap of the indigenous Urushi trees. The Urushi is applied by the hands of select Japanese artisans. Once the lacquer cures it hardens around the natural rosewood body changing its resonant frequency.

All Koetsu Urushi models use silver cladded ultra-high purity copper coils. This process involves a silver sheath being slowly drawn over the copper.

Many say the Urushi body Koetsus offer an even more exciting sonic signature compared to the standard Rosewood models.

"The hauntingly realistic level of three-dimensionality the Koetsu brought forth stunned me." Jeff Dorgay, Tone Audio

“How can a phono cartridge's tiny stylus tracing an LP's microscopic grooves make great sounding music? To me it's a magic trick that never gets old with just about any decent cartridge, but with the Koetsu Urushi Sky Blue cartridge it happens on a wildly higher level, so musical epiphanies occur on a regular basis.”

"I went out of my way to play records of questionable sound quality, a lot of Motown, Stax and very early Rolling Stones LPs that were more than 50 years old, and the 'Blue always made them sound better than I'm used to." Steve Guttenberg, cNet
