New from Robert Tucci in Germany is this set of tools for use with your tuba mouthpiece.  These adjust resistance, enhance tone and increase efficiency.

The Chops Dyno System consists of four silver plated thin-wall brass tubes of differing lengths.  These fit inside the backbore of your tuba mouthpiece.  A tubist can use these when buzzing, when warming up, during practice, or at the concert.  Leave a Dyno inserted all the time, or use for special situations.  Each Dyno includes a rubber seal at the top, but you may use it without the seal for faster change out.

Fit

  • For mouthpieces with throat bore of 8.1mm (0.319") or larger.

 

Sizes

  • CD-5 50mm
  • CD-4 40mm
  • CD-3 30mm
  • CD-2 20mm

 

The CD-5 is the longest Dyno, providing the strongest resistance and fastest response, and is the most accessible.  It is useful for both young players and experienced performers.  The CD-5 is available as a single item.

When using the Dyno, the response becomes much stronger, tonal center is more pronounced, legato becomes smoother and access to extended range is enhanced.  These are especially helpful with low register development.

When used with your instrument, the Dyno offers similar benefits when...

  • a sound with more overtones is desired
  • the performance takes place in a venue which covers the sound

Drop in a Chops Dyno to add the tonal presence which best suits the musical surroundings.  Also when...

  • the program includes a broad repertoire of compositions of different character.

Simply quick change to obtain the most appropriate sound using the regular mouthpiece.

For musicians moving from a smaller to a larger mouthpiece, beginning with CD-5 to keep the resistance when it belongs: at the point where the air meets the embouchure.  This keeps the throat open so the embouchure has a good air supply.  Thereafter, use the shorter Dynos which maintain the same beneficial function.

An added advantage with Chops Dynos is that delicate passages can be made more effective while easier to produce.

Chops Dynos are drop in and drop out.  The CD-5 is an ideal partner for warming up quietly and can even be used as a quick-change pocket mute.

Look Good Feel Good!!!
Size: XX-Large Big Tall, Color: Lilac
The shirt is verey stylish the price point is good quality is good. Ordered a size down the first time because i tried using size chart. My opinion if you normally wear a certain size in another brand you like, consider ordering that size. I say this because I ordered down one size from my normal King Size brand and had to return. New one fits perfect recieved lots of compliments on the color. So I recommend this brand and this shirt for those of us who may be on the BIG size and enjoy a little room in their fit

Color and size were great, but it came with some wrinkles and creases.
Size: 5X-Large Big Tall, Color: Olive Green
The color (olive green) and size were perfect. The shirt is comfortable, and i did not see any bad stiching. The fabric is a synthetic and it came with a bunch of wrinkles and creases. I'm hoping with several wears and washings that the initial wrinkles will smooth out -- if that happens, then I'll update this review.

Sizes differ
Size: 3X-Large Big Tall, Color: Pink
Sizes differ from each style shirt. A 3X in one style does not fit the same as a 3X from a different style even though it is the same company. The ones that I could find that fit were a nice shirt and comfortable. I would not rule out COOFANDY after trying one style shirt. To be honest I can’t remember if I kept this shirt or returned it but the return policy allows you to try different shirts so well worth the money to give it a shot. I needed a pink shirt to match my wife’s dress so I tried a couple different ones and ended up with a couple nice shirts at a reasonable price.
