Yanagisawa 66 Brass Tenor Neck
	I found this crook to be fairly similar to the 64 in tone. Perhaps a tad more edge and hardness overall, and I don't think it was quite as open as the 65. A good choice if you want to cut through! In terms of fitting these crooks on other saxes, I found that they slot nicely on to the Yamaha 62 and Custom models, but I found them to be very loose on all Selmer and Keilwerth saxophones.
