I can't believe I never had this done before. Dropped my 12-year-old Bach 37 off with Michael at Wichita Band Instrument Company. The next day he had it back to me looking brand. spanking. new. The bore of the mouthpipe looks like a new shotgun barrel. When you speak with Mike, right away you can tell he is enthusiastic about his work. When you see his work it then speaks for itself. Attention to detail is second to none. He gave me a quote to take out a few dings and look at one of the slides. He ended up doing about a dozen things to it in order to make it perfect and still came within the original quote. And it plays great! That leadpipe was a bit stuffed up when I brought it in. I am quite impressed and will be taking all of my horns to him in the future.
