Excellent quality. Band director recommended.
This mouthpiece was recommended by my son's band director. I'm very happy with the quality and price. My son said it made his trumpet so much easier to play than the mouthpiece he was using.

I purchased both the 1.25C and 1-1/2C. Both are a bit stuffy!
For beginners and for the price, the Eastrock 1-1/4C and 1-1/2C are a decent place to start for comparing these two “classic” mouthpieces, which are inspired by the traditional Bach mouthpieces of the same name. If you’re on a dreaded mouthpiece safari just know that the 1-1/4C and 1-1/2C will differ in that a 1-1/4C will have a slightly narrower rim and deeper cup versus a 1-1/2C (note that neither have as much cup volume as a “beginner” 7C and that it’s the contour of the 7C rim that some find uncomfortable... interesting, yet little known fact!). Anyway, If you want to know what a 1-1/4C and 1-1/2C feels like pressed to the lips, this Eastrock will deliver because the rim and diameter are very close to the Bachs. Where I struggled with both Eastrock mouthpieces was that there was more resistance and a difference in tone. The sound and feel was “stuffier” than with my Vincent Bach 1-1/4C (my Vincent Bach 1-1/4C is not a Vincent Bach ‘Corp.’ for those of you who know your Bach mouthpiece history and are aware of the inconsistencies in Bach’s manufacturing). I wanted to attribute the stufiness to overblowing, but that’s not it. I was determined to figure out why the Eastrocks felt and sounded different, so I put a caliper on them (for you measurement junkies): EASTROCK 1-1/2C Rim diameter 1.062”(26.97mm) Rim width .216”(5.49mm) Inner diameter rim to rim .662” (16.83mm) Backbore .327” (8.31mm) EASTROCK 1.25C Rim diameter 1.065”(27.07mm) Rim width .197”(5.01mm) - slightly smaller than Bach, but just as comfortable for me Inner diameter rim to rim .658” (16.7m) - same as Bach Backbore .327” (8.31mm) - same as Bach For Comparison (The measurements of my Vincent Bach 1-1/4C) Outer rim diameter: 1.080”(27.42mm) Inner diameter rim to rim .658” (16.7m) Rim width .213” (5.43mm) Backbore .327” (8.31mm) Overall height/length of all the mouthpieces is the same at ~3.5”. So what accounts for the stuffiness? Could be a number of things for which I don’t have the delicate instruments to measure; for example, cup depth, cup volume, throat diameter, etc. Either way, something is slightly different from the Bach. Overall, the Eastrock is a good mouthpiece for those on a budget and it makes a decent backup in a pinch… just not for a pro in my opinion. I played for 30+ years, then took a 15 year hiatus, and have just started the journey again by dusting off the ol' Bach model 43. If there's one thing I learned over the years, it's that a different mouthpiece can add color/timbre, but there is no substitute for a well developed embouchure and proper technique. Also keep in mind that what works for me may not work for you because we all have different anatomy (lips, teeth size and alignment, tongues, oral cavities)… Being a musician is a journey and you’ll need to discover what is most comfortable for you. Still, be sure to stick with a new mouthpiece for a few weeks to properly assess it!

Works great
This fit in my daughter's Jupiter trumpet without issue. She seems to like it. I don't know much about trumpets so I felt like I was taking a gamble buying a cheap one, but it seems to fit and work fine, and that's all that really matters for us. If she sticks with it, she can get the bach or the yamaha.

Gotta have a backup!!
My kid is in the high school marching band, so they give him the silver marching band trumpet (fancy). He also has the leased trumpet that he has been playing for 3 years. I wanted him to have a mouth piece to keep in the case with the leased trumpet, so he doesn't get to a marching band gig with the fancy trumpet only to find that his 3C is in the other case - which is in the band room at the school because he forgot to bring it home on Friday. (do we all have the same kid?? ) Comparing the EastRock to a Bach 3C His report as the musician: It fits the trumpet, feels, and plays no differently than the Bach 3C. My report as the listener: There is a very slight difference in timbre and tone, but it sounds perfectly fine. It is pleasing to listen to, just ever-so-slightly different. Recording 2 tracks with just changing the mouthpieces would sound like 2 trumpet players playing on 2 different instruments, with neither one sounding any better than the other. - I can't speak to its longevity, but it's hard to go wrong for like $12. - If you're looking to have a backup mouthpiece and don't want to spend Bach $$, this will get the job done. - If Bach $$ makes a big dent in the family budget, this one is more than a suitable alternative.

Ojalá hicieran una sin el cuerpo para instalar en trompeta. Realmente lo que sirve es que puedas ver tu embocadura pero tienes que inclinarte para verla porque así recto no te ves, tiene que ser de lado.

Cumple.
