“I received the new tuning slide + sound post yesterday afternoon. Your high level of craftsmanship was quite evident when I first saw it. After playing my trumpet with your slide, the best word I can use to describe the sensation is “FREEDOM”. It has the perfect amount of resistance that seems to compact my sound as well as adding some brilliance and “bottom” (i.e. lower overtones) as well as more flexibility. I tried the sound post both on the slide and on various spots closer to the valve casing. Quite frankly, the slide plays best for me by itself. However it’s great to have the option.”
