Daddario PW-CT-21 Micro Clip Free Tuner

Just put on PRS SE Custom24. It fits perfectly. You can put it on high E as showed on Daddario website, but also on B string as me. I think there is not bother your hand but you can see the display anyway. That's really a good product. Seems specific for PRS SE. Does not fit on PRS Custom Core USA hardware.

A game changer and far better than a clip on!!!

Works good as tuner and very good idea overall.
But after a few months of use, the screw broke and I had to look for a replacement 🫤
So, this one is good tuner with bad screws 🤷🏻‍♂️

I am very satisfied with these tuners, in all aspects. This specific mounting method is a bit problematic as backs of headstock are commonly crowded place. Out of my few ukuleles and bass guitars, I mounted this one on Mahalo bass solidbody "uke".
My only peeve is that there is no "underside" (clip or screw-in) to buy without tuner. If there were any, I would have a unmber of these mounts on my ukes and basses and probably a third NS Micro tuner.

No questions to the tuner itself. I have already several small D'Addario micro headstock tuners and they rocks! I have it attached on my classic guitar — not behind the head, but on the side — and it fits great.

Only thing is about the applied screws — they are cheap. I had to screw it in the wood with some force (original was shorter), and the screw head slightly crumbled under the screwdriver's pressure. I hope that I will have no need to replace it later.

I put such tuners on all your guitars. It is very convenient that the tuner is always with you, you will not forget, you will not lose.
