bauhaus Tenor trombone dual bore BT-501-D 2000's - Clear lacquer

The Bauhaus-WALSTEIN 501-D is a full outfit and represents great value for money. It has a gold brass bell for added warmth and projection. The body and tuning slides are yellow-brass lacquer. The inner slide is chrome plated white brass (approx 40% zinc). Outer slide is nickel-silver. The bell is 204mm diameter; the upper slide bore is 12.5mm diameter, while the lower is 13.2mm diameter Supplied with a hard wood shelled black, canvass covered case

In practical, physical terms a 'dual bore' on a trombone means that the upper slide's bore (the diameter nearest the mouthpiece) is very slightly smaller (1mm or so) than the equivalent bore on the lower slide. In playing terms, there is (as always) some argument as to what this means. Most agree that the slight increase in diameter leads to more 'openness': greater volume; broader sound. It is quite unusual to find such a property on a student horn. It does not alter the manner in which the trombone is played and thus is still suitable for beginner trombonists - but able to take them further than a standard tenor trombone - it is good for orchestral work.This outfit also comes with superslick care kit, Slide Grease and Cleaning Rod.
