I met Keith many years ago when I was doing studio work. There probably isn’t anyone or any place he hasn’t tuned for, including my studio. I’d never use anyone but Keith as his tuning had a certain magic quality.
One of the many amazing things about Keith is he rode his bike everywhere from job to job. Another thing is that he is 90 (video is from 2010) and still at it. Also impressive is that he has completed well over 25 triathlons and 45 marathons!
