The YTR-800N "BIG SOUND," a trumpet known to those in the know. I recently purchased this here and have been using it, comparing it with my existing BACH. As a result, I've decided to keep the BACH and let this one go. Since acquiring it, I have done the following: ・Light cleaning at home ・Repaired noticeable dents at a specialist shop ・Added a replacement (homemade) for the missing movable brace ● Features (The text in parentheses is my supplement) 〇 The following are the features compiled from online information. ※ indicates at the time of sale ・Bell weight specified at 213g ・The heaviest mouthpiece receiver in Yamaha ※ ・Movable brace included (The original is missing, so a homemade replacement is included. It works properly. I like the position in the first photo.) ・30-degree inclination of the tulip on the 1st valve slide (I didn't understand the meaning at the time, but it refers to the U-shaped finger hook) ・The heaviest water key in Yamaha ※ ・The 3rd valve slide stopper was changed from the original 800 rod to a screw stopper type (similar to the current 850 and Xeno) and made removable (also, the screw was hollowed out to reduce weight to the limit) Kiyohiro Nakagawa said at the time of release, "It's better to remove the 3rd valve stopper." In addition to the above, the bell brace position has been changed to the valve side, and the leadpipe is probably made of gold or red brass. 〇 Kiyohiro Nakagawa's comments at the time of release are as follows: ・The YTR-800N series seems to match pop music, jazz, and concert bands. ・It responded from ppp to fff with maximum power. ・It can be said that this is an instrument that "accepts power," which cannot be obtained with currently ※ available instruments. You can find more information by searching for "Nakagawa Model." The case is not included. I will ship it with sufficient cushioning.
