"Gleichweit mouthpieces are, quite simply, the very best clarinet mouthpieces I have ever played on. I have been playing them since they first appeared on the market - the comfortability, full-rounded sound, reed friendliness, and pitch make these mouthpieces second to none. I have never endorsed any clarinet products during my career, as I have always found flaws with all the clarinet products out there. This is not the case with Gleichweit clarinet mouthpieces - they leave every other clarinet mouthpiece out there in the dust - and it is not even close! I endorse them wholeheartedly"
