Noticed Ishimori Reeds on Thomann and saw positive validations by users. Personally I appreciate Ishimori products for its high quality, for sure. Am a happy blower on Yany Tenor T992 using, after quite a journey through mostly artificial blades, Hartmann Hemp 2.0 blades. That remained my best choice, until today. I ordered a pack of Ishimori Wood-Stone natural reed blades 2.5, and got these yesterday. Installed one of these and started blowing. WOW,..... that, for me, is at least 100% if not 120% of the ease, tone, vibration of my Hartmann reed. So, what stops me.... you.... ??
