CKB Acousti-Balance 7C Trumpet mouthpiece. Silver plated.
New in factory sealed plastic in display box. (See pics!)
I discovered these CKB Acousti-Balance mouthpieces about 5 years ago, if memory serves me. I have a few models of these that I play (for Trumpet: 1BW, 1B, 1½C, 3C, 7C; for Cornet: 1½C; for Flugelhorn: 1C, 3C, 7C), as I really like the way they were designed to play, second only to my Asymmetric mouthpieces.
I NEVER play 7C cup mouthpieces, EXCEPT for a CKB Acousti-Balance 7C piece! So, along with my go-to Asymmetric 3C+-544 piece, I always carry a CKB 3C & CKB 7C in my gig bag.
CKB Acousti-Balance mouthpieces were only made between 2000-2010, by Kelly (in USA), by Warburton (in USA) and by Lausmann (in Germany).
I don't think they were properly marketed as the quite phenomenally designed and playing pieces they truly are!
Tops are heavyweighty, shank has built-in weight (as a sound sleeve/collar) for dampering vibrations into backbore, focusing sound more efficiently thru mouthpiece into Horn. Rims are very comfortable, with ample width, without being too wide.
Please read print on pics of display box (pics #1, #2, #3) to know why these mouthpieces were designed as such!
I rarely have one of anything that's excellent, these CKB Acousti-Balance mouthpieces an example of this quirk of mine! I really love playing these mouthpieces and bought back-ups to back-ups! These mouthpieces are becoming rarer to find!
There are two CKB 7C Acousti-Balance mouthpieces available, both in factory sealed plastic in original display boxes, New Old Stock, in mint condition. I'm keeping a third CKB 7C, slightly used, in excellent condition.
