【Almost Unused】JK (Yamaha) Horn Mouthpiece 1DM (EX-A1)
Product Details
【Update 2026.2.20】Price reduced!
Hello! I am listing a JK (Yacht-Kar) horn mouthpiece.
The model is 1DM. The cup inner diameter is 18.0mm, which is quite large for a JK.
I have only used it a few times, so there are no scratches and it still has its shine, so I believe it is in almost new condition. Please refer to the photos for details.
This is a rare mouthpiece that is often not available in music stores, so I would be happy if it finds a good home.
Please feel free to contact me if you have any questions. (^^)
