Why are their alto models are more demanded than their tenor models? Is it because there were more famous players used the alto mouthpieces? Anyone out here used/are using the tenor mouthpieces? Please share your experience. Thanks.
Leaving market value (real or perceived) out of it, the reason Meyers and Gregorys are sought after for alto and not so much for tenor is the same reason vintage Links are desired for tenor and not nearly as much for alto - the designs are just more complimentary to the popular voice of the horn. Not to deny that there's a good share of "As Coltrane or Desmond did, so shall I."
Wouldn't surprise me if NY Meyers are more rare for tenor than they are for alto, but because the Meyer design just "works better" for alto in a general sense, the desire to obtain them (and their resultant market value) is greater. Having said that, I've had a tenor Meyer play as smooth and as lush as a great Link - they just usually don't!
