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.

Stable, attractive, and easy to turn into a table with your choice of top
Size: side table leg
The X-shape of the table legs - constructed with solid metal flanges, T-joints, X-joints and 1-inch diameter pipes - provides a strong and sturdy base for a wood top. The legs have adjustable feet pads to prevent scratches and ensure stability. Assembly of the legs is relatively simple (the instructions are clear) but you will need your own tools to attach a top. The industrial design is especially well suited to rec room or finished basement use. I am adding a 28" diameter raw edge slab of wood from a recently felled tree as the top and it is very attractive. (Photo unavailable because after I made certain it would work I sent the slab out for drying and finishing.) If you want a custom table and have a particular piece of wood you want to use, these legs are an excellent choice.

Very nice kit: Beware it is NOT heavy duty plumbing pipe though!
Size: side table leg
I want to give this kit a high rating, but I need to address the "truth in advertising" bit since there may be an important disconnect between what you think you are getting and what actually comes in the box. Black plumbing used for shelving or table legs is part of an important niche in interior design. I like the industrial loft look myself and have a variety of glass, steel, and masonry elements in my home. This kit fits that look and provides plenty of "strength" for most domestic uses, like shelves or coffee tables. But they are NOT "industrial pipe" or "maximum durability pipe." Note the phrase "cast iron finish feet," which together with the other claims might lead you to think these are cast plumbing fittings. They are NOT! The feet and flanges feel like electrical conduit fittings, and the pipe sections are likely aluminum. They might be electrical or they might be multi-use, lightweight pipe. While all this might lead you to think that you're getting a truly retro, heavy-duty pipe kit made of black plumbing pipe, you are not. But, does it matter? Depends. I find the lighter pipe's smooth finish a nice "tone-down" from the rough plumbing look. All together, this kit provides plenty of strength for most furniture and the rustic pipe look, but with a nicer, lighter finish. To me that is a plus--this is a very nice kit and costs less that if you'd pieced it together from real plumbing parts (I priced it out to compare), and looks retro but cleaner. I knew what to expect because while I got this kit free on Vine, I had purchased a nearly identical kit from another seller last year. So, I'm giving it 5 stars for what it actually is and for the price, JUST BE AWARE THE NARRATIVE IS MISLEADING. Which is unfortunate because just like some people might want the heavier pipe, I'm betting more would be attracted to the look with a cleaner, lighter feel.

Great addition to our home
Model: Model B with Removable Tray
Putting together took a little time but instructions included were easy for me to follow. Putting the screws in for the shelves required a little work to get then started but nothing that I would say would be a problem to do. It is very sturdy and looks great in our room we are transforming into a hangout/bar area. I can't wait to get all my accessories in to add to it and display all my nice bottles I have. Great cart for the price.

My Cart Worked Out Perfectly For Me - Update: I got a second cart
Model: Model B with Removable Tray
Delivered sooner than promised. All pieces were present. All parts were in good condition. Assembly was done by a professional who thought the product was well done and needed very few adjustments. The cart rolls smoothly, is very sturdy, is a great size, looks attractive and is perfect for my needs. I would order one of these again. Update: I did get a second cart and I am just as happy with this second one as I have been with the first one.
