Thank you for viewing! As you can see below, this is a rare part for a Rath trombone user. I believe that those who can utilize this are also Rath users. I will consider a reasonable discount, so please feel free to comment. This is a Michael Rath trombone tuning slide. Material: Gold brass Compatible with R3 and R4. There is some plating剥がれ (peeling) due to scratches from about 2 years of use, but there are no dents. The normal material is yellow brass, but this is gold brass, which is available as an option. You can feel that the tone is a little warmer. If you combine it with a yellow bell or nickel bell, it will be a setting that adds a little resonance to a clear tone. (I was recommended this at the store where I bought it, and I actually compared the sound, and I thought it was more cost-effective than changing the bell) I am selling this because I have purchased a different part and have less opportunity to use it. Currently, if you buy a new one, it is very expensive and the delivery time is also long. They say you should expect to pay over 100,000 yen due to the strong pound. Please consider this opportunity. ※ Although it is a beautiful item, it is a used item, so please understand that it is NCNR (No Claims, No Returns). Please refrain from purchasing if you are sensitive to such things.
