I was supposed to give a complete list of professional trumpets?
A professional can play a student trumpet, but he will feel that the trumpet is fighting against him in various ways, such as in bore size and in tone and in fingering speed.
For example, I had to give up on student-level instruments a couple of years ago because the student-level instruments sounded like they were literally coming apart at the seams when I blasted very loud G's above High C through them.
As for being a beginner, I began in 5th grade, played in band for 5 years through Junior High, then continued on my own for another couple of years after that, finally working out embouchure problems via Reinhardt and experimenting with various mouthpieces.
My comeback started about 5 years ago, when I played a High C within a minute or so of receiving a trumpet as a Christmas present.
I have experimented with a multitude of different trumpets and cornets, plus a multitude of mouthpieces before finding what suits me, so that I now play scales and ballads up to G's above High C's (with very little mouthpiece pressure) that can be heard a block away even though I have all my house windows shut.
(Last year I squeaked out a couple of tiny Double C's with a Wick 4E.)
In Junior High I started on a cornet, brand I don't remember.
Then after I dropped out of band I switched to trumpet, brand I don't remember.
In my come-back I have owned, in the approximate order that I owned them showing progression from student trumpets to semi-professional trumpets as my embouchure matured, Getzen 300, Holton 602, King 601, Yamaha 2320, Bach 300, 1952 Conn 22B (it was falling apart but sounded incredibly great), Holton Galaxy, 1970 Conn 22B, Holton Super Collegiate (an intermediate level instrument), Conn 5A (professional level), now looking for a replacement 1940's-1960's Conn 22B in very good condition.
As for mouthpieces that I have owned, both 30 years ago and recently, Bach 7C, Schilke 6a4a, Holton MF3, Marcinkawhatever 3C, Bach 3C, Weril W46, Bach 3E, Schilke 13a4a, Schilke 14a4a, Schilke 14B, Schilke 15B, Schilke 10a4a, Yamaha 11E, Yamaha 13E, Yamaha 14E, Curry 7Z, Curry 60M, Curry 50M, Curry 40M, Bach 7, Bach 7E, Bach 7D, Conn 4, Conn 7C, Holton 66, Holton 77, Wick 4E.
Any embouchure problems I am experiencing right now are due to the fact that I am playing a new instrument with a radically different bore size than I have ever played before, but practice is slowly eliminating the problems and rapidly getting me back to where I was on the previous instrument.
My weakness is that I don't read music all that well, so I tend to stick with slow ballads.
Over the last 40 years I have about 12 years playing experience.
So I am an untalented amateur, but I don't consider myself a beginner.
I am able to understand many embouchure problems and advise others on how to deal with them because I went through many, many such problems over the years before finally fixing them all in my own playing.
So I can advise on problems with upstream embouchure versus downstream embouchure, bottoming out problems, effect of using different mouthpiece diameters and cup depths and cup shapes and throats and backbores, rim shapes, mouthpiece pressure, increasing range and endurance, Reinhardt basics.
I am unable to join any kind of community band because I have a chronic illness that is worsening year-by-year leaving me permanently handicapped and strong enough to play for only 10 minutes at a time. But I continue playing on my own because it gives me joy and satisfaction.
