Comparing Grenadilla and Cocobolo bells and barrels for BACKUN Q and F model

I was asked by Dolce Musical Instruments to select a few clarinets for them.
You can purchase these instruments from them. If you write them an email they will help you to get one of these amazing clarinets.

Listen the differences between the small/big changes by the bells and the barrels.
