Ive had a mcvay bender in my main tele for a few years now, and a mcvay bender in a backup Esquire. Smooth silent operation, the saddle stretches the string, rather than pulling from the saddle like the Parsons style sawing across the saddles. His machining is impeccable, and he is a fantastic guy. The tuning stops stay precisely in tune even after string change. I have another tele that I will never play unless it has a bender so, I got it to him yesterday. I am very excited.
