Yesterday I finally had a chance to assemble and tune the Shime with your heads and play it for an hour. Since the heads are pretuned to a high pitch already it was easy work. The sound is incredible, very loud and cutting but with a nice clear tone. And the look is just great. Good work! I will recommend your quality to others. The poplar bachi also feel good. They are the lightest and also shortest I have which makes them especially suitable for fast playing. I also like the rounded tip.
