We are extremely excited to be offering this incredible Classiq setup here at Austin Custom Brass!

This listing will configure one full mouthpiece with individual components (one rim one cup, one throat insert, and one backbore).   In the next few days and weeks we will have additional listings for each individual model.  With any purchase here ACB will send out a rapid prototype one piece mouthpiece at no-charge while you await your kit setup.   We can also make these as one piecers at a slightly lower cost.  Please email us  or call 816-410-0826 for more specifics there! 

Classiq™

Find a better fit.

Classiq exists for one reason: to help everyone find a better mouthpiece fit.

The Classiq system allows interchanging 4 components:

• a screw rim

• a screw cup

• a throat insert

• a screw backbore

This allows for an unprecedently rapid fitting and testing process. The kit shown here, available at Vennture HQ, trade shows, retailers (coming soon!) and for private rentals for fitting events (like academic trumpet studios) can be configured into 13,500 unique combinations. It can accommodate all your trumpet needs – from a tiny cornet-shank piccolo setup to a giant bathtub cup and rotary trumpet backbore, an anything in between.

Now you can dial in your setup and test it, then tweak one element at a time. Think about it: have you ever tried your exact mouthpiece one throat size bigger and one throat size smaller? What if that tiny tweak improved it? You’d never know – because each of those tests would involve a special order non-returnable mouthpiece with a 6-week or more lead time. But now you can swap out throat inserts in 15 seconds and know right away. Ditto for

• smaller or larger rim diameters (moving left or right in the racks)

• shallower or deeper cups (moving back to front in the racks)

• different rim profiles (5 different contours for each rim size)

• bigger or smaller backbores (choose from 5 piston trumpet, 2 rotary trumpet, and 2 cornet shanks)

Composition of the Kit

Screw Rims: 5 Inner Diameter Sizes X 5 Contours

There are 5 different inner rim diameters in the fit kit. They are:

• 0.620″

• 0.630″

• 0.640″

• 0.650″

• 0.660″

Note that these rim diameters are measured at 0.095″ (2.41mm) depth from the crown of the rim. Note this is also where Parke measures their rims, and the threads (0.765″-36) are the same as well, so a .640″ Vennture rim is compatible with Parke 640 cup or underpart, and a 640 Parke rim is compatible with a .640″ Vennture cup. The following

Note that Marcinkiewicz measure their rim diameters ar .032″ (0.81mm) from the rim crown, and many other manufacturers measure theirs at .05″ (1.3mm) from the rim crown.

• The P rim is a slightly flatter orchestral rim with crisp inner bite and more outer support than most. Parke fans may find it comfortable.

• The Q rim has a very well-supported inner bite, making it play a bit smaller and with more rim support than other rims of the same nominal size.

• The R rim is well-rounded on the inner rim in a way reminiscent of Bach and Greg Black designs, but with a bit more outer support than a typical Bach rim.

• The S rim is very well-rounded on the inner rim for easy lip engagement but then peels away crisply to form a second bite. Fans of Stork Vacchiano rims may find this familiar.

• The Z rim is a very wide supportive cushion rim. The inner rim is very rounded and the high point is farther out, funneling the chops in rather than wedging them apart. Reminsicent of (but in no way identical to) the Neill Sanders deisgn concepts of the 1960s and 70s and then used by David Hickman’s later designs.

Screw cups begin right  where the rims leave off at each of the five inner diameters listed above. There are 6 cup volumes available for each of the 5 diameters – for a total of 30 screw cups in the set. The cup volumes are:

Note that we talk in terms of cup volumes rather than cup depths or shapes. An interesting thing happened while we were designing Classiq™ in VennCAD™: we found that familiar shapes just happened as we attempted to hit certain volume targets at certain rim sizes while holding the throat point constant. So instead of “that looks like a (Bach) C-cup” or “that looks like a B-cup,” they just happen that way as the walls are bowed out and the floor pushed down to dial in a particular volume.

Talking about volume, and keeping it consistent between different rim sizes, means that, for example, a .07 cu.in. cup in a .630″ rim diameter will be deeper than a .07 cu. in. cup in a 0.650″ rim diameter. This is as it should be – the two are more acoustically similar than two cups of different rim sizes with the same depth.

The screw cup interfaces with the throat insert at a depth of 0.45″ (11.4mm) from the rim high point and a diameter of 0.182″ (4.62mm). From there, the Vennturi (get it?! It’s a venturi [i.e. fluid flow choke point] made by Vennture!) is engineered to taper smoothly down to the selected size, maintains that size for the designed cylindrical length, and begins the backbore flare up to a diameter of .173″ (4.39mm), which occurs at a point of depth of 0.9″ (22.9mm) from the rim high point.

These throat inserts are made in the following sizes:
