I sent my horn for a valve alignment and have had it back for a week and a half. All I can say is wow! I can really tell the difference. The horn feels so much better. I was considering buying a new horn, but my trumpet teacher told me to try the alignment first. I am not a "gear head" and I don't like to blame equipment for my own playing deficiencies, so I was skeptical. My teacher is a knowledgeable trumpet player with many years of teaching and performing experience. Before I shipped the horn (Bach Strad circa 1984) to Bob Reeves' shop, I recorded myself playing through some scales and studies I am working on. When the horn came back, I immediately noticed better intonation and endurance. I recorded myself a couple of days later and the difference was like night and day. I mean the recording sounded like a totally different player. The tone was more centered and in tune. I love my sound so much that I am not considering a new horn anymore. I plan to invest my money in a new tuning slide from M/K Drawing, some new CDâ€™s and more lessons. If anyone is considering a valve alignment, I highly recommend Bob Reeves. They are very professional and reliable. Thanks Brass Spa for the great work you did on my horn.
