Gotoh GB10 4L N Bass Tuners

The tuners ring very badly when you slap or even tap. It makes acoustic practicing almost impossible. They also rotate freely a bit before actually engaging and pitching up or down. I thought Gotoh was a serious company with actual quality standards. I am very disappointed and would gladly return the tuners but unfortunately installed them late after received my order and missed the 30 day period. Have to start looking for a better quality replacement now. I am not pretentious about instruments and gear and would accept the sloppy rotation but the ringing is truly horrible.
