Yamaha YMP-204MS  Marching Mellophone Silver

Purchased new around 2009 and used for about a year, then stored at home. I checked the sound output periodically during maintenance. It was also checked for sound before being exhibited. There was no problem.

Piston -> No problem.

Extractor tube -> There is a sticking in the 3rd tube. We had a water key, so we did not mind using it. The other extractor tubes are fine.

The bell has a slight dent that is streaked if you look closely, but it didn't show up well in the picture (see photo #6). (See the 6th photo).

With hard case

Mouthpiece included (YAMAHA MP 14F4)

Repairs and other maintenance should be done by yourself.
