Bach Advertising – Bach Artisan Collection (Video)

I’m glad.
I am a Korean person who is interested in Bach trumpet.
I would like to know the history and specifications of Bach Omega Trumpet.
I recently bought an Omega Trumpet on eBay
I have never used it. I want to know.
I used the Stradivarius 37 model in high school.
