I now have two of the D'Addario Micro Tuners. One has been on my Strat for years, this one may end up on the Tele. Of course, it's always in tune so may not need it! ;) I also have the Joyo version which usually is on a Gretsch. They work wonderfully. Clamping it "upside down" under the headstock near the nut keeps it in view to the player and almost invisible to the audience. Ease of use: quick and accurate. Very handy and preferable to Snarks and the myriad Chinese tuners, although they (Chinese) do work just fine and can be picked up for a couple bucks these days. I'll spend a couple more and get the D'Addario Micro Tuner.
