Model GM Cup

"Master of colors" for Geyer model horns.  The GM marries a medium-deep cup with a #19 bore to give you the most control of the sound color of any mouthpiece we offer.

This is a model I didn't want to release; we already have the G and GS, an excellent pair of Geyer mouthpieces that cover a wide range of playing.

It also does nothing to broaden the market appeal of the range - with no counter to inquires like "why are all your bores so small, I play a 12 and the largest thing you have for Geyers is a 16"*.

The design though had other ideas.  I made a few of these as a one-off back when I thought "oh we'll just offer different bore sizes of the models, that'll go fine, everyone else does it"** and I sent them out to some testers. Technically this is just a smaller bore GS.  Or just a deeper model G.  The truth though is it's an American shank Model M.

In practice it's none of those, it's 100% it's own design and one too good not to release.  It falls between the G and GS in the slotting / slurring trade off, it plays in all registers well (as any released mouthpiece of ours must), and it has an overall nice feel.  That's not enough though to say "blow up the roadmap, abandon common sense and release this model".

It's super power is the mastery of sound colors you can produce with it.  You can control volume and color more independently than with any mouthpiece I've tried before and you can go from very diffuse to very direct in pretty much any register or volume. The G and the GS do this well, but the GM is the "master" of tone color.  The name is also a nod to master of the horn, my teacher, and brave model tester; the great Larry Williams.

So with that said, how do you pick between the 3 G-series models for your Geyer-family horn?

• Do you need a bright, crisp sound all the time and the ability to punch through thick orchestration?  Does your horn run a little dark?  Model G
• Do you want the smoothest slurs and sound you can get in an efficient all-day-session mouthpiece?  Model GS
• Do you want the most control over the tone color possible?  Model GM

* The answer is the backbore geometries are pretty different than a lot of "standard" American designs and throat sizes aren't a great way to measure the feel.

**Story time - the original GS was in a #14.  Literally nobody liked it - the highest praise it managed from any tester was "This is the least worst mouthpiece I've tried on my Geyer, but I'm still playing my Conn tonight".  It's the worst playing mouthpiece we've ever produceed and for no obvious reason whatsoever.  The temptation is to just say "oh it's too deep and too open" but the Model C is deeper and more open but plays way better on every horn.
