Hey all. I have a 2 year old lacquered Xeno (8345G) that has developed some lacquer problems on the lead pipe and nowhere else. I always wipe the horn down after playing. I'm not sure what has caused this.

Yamaha has a 5 year warranty so I'm sending these photos to the dealer that sold me the instrument. They think Yamaha will take a look.

Any ideas as to what has caused this? Why is it not happening elsewhere in the horn?

Hi ---- I'm gonna take a stab at this with this quote directly from Roy Lawler's web site: "the large companies put the finished assembled trumpet in a ACID etching solution to remove excess solder for speed. This is why some trumpets have red rot problems as they are left in to long. The strong acid pulls the zinc out of the brass."

I previously played a Yamaha 6345HS for a long time. In the process of shopping for a new horn, I opted to go with the Lawler TL6 (w/1A lead pipe), primarily because I would rather spend my do-re-mi on a hand crafted instrument than a mass produced one. Essentially, the price is the same.

anyway... best of luck to you. I hope that Yamaha honors the warranty and remedies the situation for you!

Hi!

I have the same problems with my Yamaha 8310Z. There are small spots on the leadpipe near the valve casing without lacquer. I don't know why?

Hi,

I totally agree with this point of view... If we exclusively buy mass produced instruments, we'll manage to kill most of the craftsmanship. It is also really surprising to see that some of those handcrafted intruments can have the same price tag.

small spots on the leadpipe make me think more about red rot than quality control issues. The leadpipe is normally out of a relatively thin brass. When that starts to corrode (generally because of lack of cleaning) the corrosion eats through the pipe and that causes a blemish on the outside.
Get a good bore brush, clean out the horn and then inspect the inside of the leadpipe. If you see "roughness" on the inside at about the same location as the outside, a new ledpipe is in order. Some saliva/eating habits result in a more aggressive corrosion than with other people.
Get the horn checked out. 2 years is enough time to rot through a leadpipe!

Thanks for all the replies. I'm still waiting to hear from Yamaha. We'll see what they say.

I have a similar issue with my zeus, but around the bell bead. It's not red rot, b/c the spots are slotchy and black. Same problem? Would stripping my horn save the bell?

"Save the bell", sounds like a charity drive!
Blotches are not a sign of the bell desintegrating - it is a sign of the metal not being pristine before laquering. It is merely oxidation under the laquer. Stripping the horn just means that the ENTIRE surface can now "oxidize"!

rowuk (or any body else),

Any "home remedies" on how to strip the laqcuer from a horn?

Thanks

put it in the dishwasher on HOT. take out all the slides and for sure the valves, et. al. We did this to a beater cornet. I prob wouldn't do this to a good horn. But - yeah - a bucket of really hot water is another one of those home remedy, DIY'er things I've heard of. Honestly though - if you really care about the horn - take it to a professional -- you get what you pay for.
