Amazing Value

Mona AliresOctober 10, 2025✓ Verified purchase

Works great especially for the value! The tone sounds vibrant and dark at the same time, and perfect size for someone with a bigger embouchure. Read more

Shockingly good mouthpiece

Tommy GFebruary 26, 2025✓ Verified purchase

I was not expecting much for the price, but i figured I would try it out for hell of it. It has performed great for me so far, and the coating is great too. Not too much else to say here, just a solid mouthpiece for a ridiculously low price. Read more

Awesome Dennis Wick look alike

Thomas w LindstromJune 1, 2025✓ Verified purchase

Awesome Dennis Wick knock-off. I don't know how it compares playing wise I just know I have clearer pedal tones than with my 6.5AL. This is a larger cup and deeper cup than the 6.5AL so I assume its a legit 4AL. Nice polish in and out. I looked at this for several weeks, pondering because some of these knock offs don't do a good job in the cup for polish but Eastrock definitely ROCKS! If they made anything a bit larger I would try that in a second. I worked in a machine shop running a CNC lathe, I know how cheap something like this can be made. Its a shame Americans have to overprice their goods way beyond a legitimate profit margin and invite competition like this that undermines their future. Seriously. This could easily be made and marketed in the USA for $50 and the Chinese wouldn't bother copying it. Read more

Nearly perfect

JrhoadesMarch 10, 2026✓ Verified purchase

While the fit and feel is spot on, the overtones fall alittle flat as in muted nit intonation. If you’re looking for a mouthpiece to try out before spending money on a new size then by all means get this. It is 100% playable and new players will probably not notice the difference Read more

A good backup

E. StevensonOctober 2, 2025✓ Verified purchase

This mouthpiece is great for higher notes and brighter sound. I've only been using it for a couple months but it's holding up well. It's my backup and I only got it to see if it helped my endurance (it doesn't) but it's great to switch to a nice cool mp in a long concert. Read more

Hmm, Feels Like a Schilke 51.

Rod A. RodriguezFebruary 25, 2023✓ Verified purchase

First Impressions: PROS- 1. LOOKS like a Dennis Wick 4AL mouthpiece. 2. Feels like a Schilke 51 mouthpiece. 3. Sounds a bit darker in tone than the Schilke 51. 4. The cup seems slightly deeper than the Schilke 51. 5. I can play the lower tones of my Yamaha YEP 642 (large shank) Euphonium easier with the EastRock than with the Schilke 51. 6. This EastRock 4AL is a large shank (not a small shank) mouthpiece. I intended this mouthpiece for a small shank euphonium (F.E. Olds & Sons Euphonium-Baritone)... oh, well, surprise! CONS- 7. I never felt confident about the specifications and descriptions listed for this EastRock 4AL. I felt as if I was taking a gamble in buying it. 8. The rim is slightly more edgy, unlike the Shilke 51D's rounded (more comfortable) rim. Final Thoughts: 1. The EastRock 4AL is a pleasant surprise and worth the price (at this moment). 2. It is comfortable and easier to play across the instrument's practical range (I don't know about the high range). 3. I would recommend this mouthpiece to musicians on a budget wanting to try deep cup mouthpieces. Read more

Why I Wasn't Satisfied

Josiah WatsonMarch 17, 2025✓ Verified purchase

It is a 5 star mouth piece, but the only problem is that the shank was too big for my trombone. Read more
