„From the moment I tried Harry Hartmann’s Fiberreeds I’ve been able to get a strong, consistent sound across the entire horn – with real core, even in the higher range. In addition I’ve found that the reeds remain strong for longer periods than traditional cane reeds and each reed I’ve tried seems to be usable – no „duds“. If you’re searching for a reed that can provide you with a strong, full sound across the entire instrument you’ve got to try the new Fiberreeds.“
