The King model 603W is made in the USA and features a standard long bell design. The 603W also features a Shepards crook design which offers the player a Cornet with less restiance and a mellower sound. Professional Monel pistons provide light, quick action while the rose brass leadpipe warms the sound and resists corrosion. The 1st valve thumb saddle makes for easy intonation adjustments. This 603W also has silver plating instead of the clear lacquer finish for a more dynamic performance sound.
