&ldquo The new Flex mouthpiece is an amazing development on the part of K.O. at the Brass Spa.

I have been playing on the Traditional Flex 1C with the #6 backbore and found it to be very in tune, slotted, and even through all registers. The sound is big and rich with sparkle. The colors work so well in the orchestra fitting in with the strings, winds, and brass, and I have found that to be one of the biggest challenges playing in an orchestra.

I would highly recommend the Flex mouthpiece to anyone looking for a tool that gets the job done and makes you sound great doing it.

Thank you again K.O. for making my life easier and more enjoyable.
Keep up the great work &rdquo
