The Polaris adjustable barrel is made from a whole piece of aged grenadilla wood. Patent-pending technology and a special redesign with O-Ring allows the clarinetists to adjust pitch with the simple turn of the center ring without air leak. There is no gap created by in the bore as you no longer have to pull out from the tenon. The length is adjustable from 64mm to 68mm for fine tuning and use on Bb and A clarinets.
All Polaris models have a slightly tapered bore for maximum response, resonance, projection, and depth of sound.
Designed for all Clarinetist in Solo, Chamber music and Orchestra playing. This new design is completely different than Pause Schuler - Germany and any other brand in the market .
