Yamaha 2330 - blow very stuffy - any advice?

desmo

hi all,

I usually use a yamaha 6335 and I recently bought a 2330 to use like back-up horn. The 2330 it looks great and have a very goode valves. The sound is good for a student horn.

my only concern is that it blow very different from my 6335. The 2330 its' very stuffy and difficult to me especially in high register

any advice? is possible to do an easy tweak to the leadpipe? or change the main tuning slide? maybe a mouthpiece with a larger throat?

thanks

regards

Design specs, quality control, flaws, gap, age, cleanliness, etc... Take your pick. Likely a combination of most of the listed.

I would say getting two different models, or even like trumpets, and expecting them to play the same is the problem.

I choice the 2330 (trumpet) because is the more cheaper yamaha available and only like back-up horn. I bought it new, so is very clean.

anyone have tried or have some result in changing the GAP using harrelson shim kit? it make sense on a cheaper student trumpet?

mouthpiece with a little larger throat may help?

different main tuning slide from another student model? (example the previous 2335 or 2320, etc..)

Try your mpc with bigger throat , I use the same horn in a marching band I play and I had the same problem but when i start to use a Reeves P9 with #26 bore (i use a stock #27 to my Lawler) it feels much better and open .

The 6335 is quite open for a Yamaha horn. It has a lot of Yamaha characteristics, but definitely more open. That is why I have one. It is my backup horn. I have a 4335 that I played for years, but it plays tighter. I assume the 2335 is along the line of most Yamaha student and intermediate horns. They are a little tighter, particularly as you go higher. Some of the teachers here can better tell you, but I would assume that it helps people starting out to have a little more resistance.

Check or have a tech check your valve alignment.

Check all tubing for any obstructions - use a cleaning snake, or flexible plastic rod, etc.

Valve alignment. remove the valve slides and look. Also loosen the top valve caps and check if additional slight UP or DOWN movement affects the the valve-up position.

I second Steve Hollahan's suggestion. I traded a 6335 to a friend for an Olds Super. The Super was really stuffy, but I hated the 6335 so I went for it. I checked the valve alignment and they were quite a bit off. I realigned them and WOW! It became my main horn for years until I got a Super Recording.

A leaky water key can stuff a horn up pretty bad

As a practitioner of precision valve alignment I can attest to the wide range of misalignment I’ve witnessed. In addition, a fresh flat natural cork can do wonders to restore a trumpet’s response. 😉

Similarly, I play a heavywall 6335 mk. II, which is quite open. My backup horn is a 2320 (the model before the 2330, close enough), and its upper register is stuffy and sharp. I think that's just inherent to Yamaha student horns. Oddly enough, I've had some success by using a tighter mouthpiece. These horns can scream up high if you can leverage the tightness. Otherwise, drilled out mouthpieces have also helped me a bit.

Why bother you face uncertainty with any changes you could sink 1000 dollars into this horn trying to make it better and fighting it all the way.

You dont start with an AMC Gremlin and then change the engine the transmission the steering and the suspension in an attempt to create a backup nascar racer out of the gremlin.

You start instead with a car with good potential and modify that.

There are plenty of people who want to own a good student horn, they are students. Sell it on to a student and sink your money into a horn with good potential for improvement.

I dont think you will need to make any changes to a better horn

You will do them a service and yourself too.

It was a good plan to go for the Yam but it didnt work out, now is the time to cut losses and move forward.

I received some answers from people that don't even have read what I'm looking for ...

I'm happy with my 6335. I'm trying to have a similar resistance from the 2330 (backup trumpet).
YES, I'm aware that one is a student and the other is a professional trumpet and NO, I'm not looking to have a 2330 that sound like the 6335

I only would like to be able to switch between the 2330 vs 6335 without feel the big difference I find today (stuffy in the high register in case of 2330)

anyone whave tried to open the venturi to the 2330? it make sense? too risky?

thanks
