Trial Policy for Clarinet Barrels

Because of the high standards of manufacture, all of the barrels above are practically identical. However, certain ones will play better with certain instruments. Because of this, your best option is to purchase multiple barrels and keep the best one. We would recommend trying a few wooden and a few Delrin barrels – at least two of each. Simply send back the unwanted ones, and your card will be credited.

Barrels are available for trial for seven days after their arrival. Barrels returned in good condition and postmarked within this trial period will be credited back to your card, minus a 3% restocking fee.

Designed for all Clarinetist in Solo, Chamber music and Orchestra playing.
