Asymmetrics have earned a United States patent specifically for their ability to extend the trumpet range (Patent Number 5353673). This is an historical first!

THE MODELS

The model numbers can be thought of as rounded engineering indices representing upper and lower half-cup geometries and cup depth, on a scale of 1 to 5. The "Lead 342", for example, has a fairly conical upper half-cup compound curvature, a substantially reduced lower half-cup compound curvature, and a medium cup depth. Models are as follows:

AVAILABLE NOW!!!!

The LEAD 342M
with pouch and brush - $73.00

If you're one of those power players who likes to put a little more air through his mouthpiece, we're offering the Lead-342M
(for modified). The Lead-342M is identical to the Lead-342 except it has a shorter (0.100 in) cylindrical section below the throat and a smidgen larger backbore. This mouthpiece will go up to double C without breaking up and can deliver (depending on the player) just a hair more power over the complete acoustic range. But, it takes a little more air and is a little less resistant. If you're into super paint-peeling power, and need a tiny bit less resistance, the M has it. Testers were split on this, so we decided to offer both.


The LEAD 342
with pouch and brush - $73.00

The ultimate embodiment of the concept, having laser-like cutting power and a bright, full, brutal sound. Designed for demanding high register performance, with semi-flat upper rim, medium cup depth, 25 throat (.150") and dual, modified straight backbore for a good low register and a bigger altissimo sound. Effective in any playing situation, but most appropriately applied as a lead trumpet mouthpiece.


The 3C+544
with pouch and brush - $73.00

Similar in design to the Opera 545 but effectivly slightly shallower due to more cup/backbore separation (longer cylinder) with much less weighting, a different backbore configuration and a slightly different rim geometry. These design features tend to produce a little brighter sound than the Opera 545, but without the edge and cutting power of the Lead 342. Slotting is also a little less for more overall, non-specialized performance requirements. They also incorporate the intonation and ease of playing frequently associated with a 3C. But this is a 3C "plus". The plus means easier high-register, more endurance and several additional semitones of high range. Like the other Asymmetrics, the throat is open (.150") for a bigger sound, but not to the point of adversely affecting endurance or intonation. And, the cup and backbore have been balanced. Definitely the mouthpiece of choice for players requiring a mouthpiece for more all around application, and light years ahead of the competition. Band directors, start your students on Asymmetric "3C+544"s to avoid the unnecessary handicaps of poor range and endurance. And, switch your more advanced players to Asymmetric "Lead 342"s and have a powerhouse trumpet section in a few months!!


The Opera 545
with pouch and brush - $73.00

For Symphony players, Jazz players and others desiring a less aggressive, more legitimate sound with good projection, but somewhat less edge than either the 3C+544 or the Lead 342. The upper rim has a well defined inner edge for reliable upper lip suspension, good flexibility and clean attack. The rim surface is semi-curved with a slightly higher inboard surface, and slightly softened outside edge for comfort and endurance. The bottom rim inner edge has also been softened to improve low-register performance and flexibility. The #2 Schmitt style backbore, effectivly deeper cup (minimal cup/backbore separation) and 25 throat (.150") along with massive cup and shank weighting tend to provide excellent slotting and a somewhat darker, more Teutonic sound, ideal for symphonic, operatic or jazz performances. Enhanced range and endurance are here too, just as with the Lead 342 and 3C+544. This combination of features in a legitimate, orchestral mouthpiece is unprecedented!!
