Hearkening back to Vincent Bach s early 192 s New York designs Artisan mouthpieces combine the playability of Bach s Classic inner cup dimensions with the softer rim designs and greater outside mass of his early mouthpieces. These mouthpieces come standard with a 24 backbore and a 27 throat. Both of these design elements significantly differentiate the response and sound clarity of the Artisan series from the Classic Series.
