I just don't know if I'll use one of these (maybe...sometimes...or maybe more than sometimes...??) but I will personally use the other one a LOT.
I'm considering producing BOTH of them and offering them to the public (??)
One is (and I've NEVER offered ANY SORT of "Helleberg" type of mouthpiece before...) a "Helleberg 2" style of cup, YET with my (most popular RIM PROFILE in my mouthpiece line) #2 profile rim. Further (as I just have always found this style of mouthpiece to sound slightly too "terse" for my personal taste - I altered (NOT the throat, but) the back-bore to subtly "tame" its sonic characteristics.
(I personally neither care for the flat rims on the 120-style Helleberg mouthpieces nor the wide/center-pointed-into-the-face rims on the Hb2-style mouthpieces.)
The OTHER one is a very shallow cup mouthpiece (shallower than my "Solo" cup) which I will use (immediate decision after very briefly testing

I'm thinking that (if produced...??) the H2 style mpc will be offered with standard and euro shanks, and that the shallow up one will be offered with small and standard shanks.
I'm also considering ONLY making these as a NO OPTIONS - other than two shank sizes - (simply) one-piece silver-plated brass mouthpieces.
The exterior of the possibly-to-be-produced ones will be more like the exterior shapes on my other mouthpieces (and NOT the old-school "German-or-1930's-Helleberg" exterior shape seen on these prototypes.
If (??) I explore production, I'm probably going to offer an introductory "first run" price (lower than the price of subsequent runs), the "catch" being that there will be no "trial" offered and if "you buy: you keep".
Again, I've NEVER been a "Helleberg" fan, but I like THIS one (rim profile + slightly smoother sonic characteristics) much more than any of those various Hellebergs in my sock drawer.
the shallow cup one...WOW !!!

With my self-built F cimbasso, I've been able to play a "trombone" high-B-flat/C (perhaps a bit higher?), but this mouthpiece offers (at least: me...and I don't consider myself any sort of tubagoddhh) "no-strain" execution in that range, YET still full access to the very-very low range... ALSO, it helps the cimbasso to sound EVEN MORE like (well...) a trombone.
LOL...There's still a trace of buffing dirt (see pics) on the shallow-cup mouthpiece...I'm going to see about plating it, today.
I'd obviously like to use it on my just-before-Valentine's-weekend pops (big-band-plus-strings-and-solo-vocalists) concert, whereby I'm covering the 4th trombone book on the F cimbasso.
Whether-or-not there's any interest (??) in these, I'm probably ONLY going to discuss them (prior to any possible production) on THIS website.
