Try using a tuning fork and tuning by ear when you’re playing a gig, or in a noisy session or jam in a pub…

I don’t want anything hanging around on my guitars’ necks or headstocks which isn’t in active use, so off come tuners and capos when I’m not actively tuning or playing capoed. Nothing looks more goofy than capos or tuners clipped to headstocks seemingly permanently IMHO, and I hate to see that. I also place my tuner at the front of the headstock where it’s easily visible to me, and doesn’t get blocked from my sight by my hand on the tuners. When I’m tuned, off it comes.

I have a whole host of clip-on tuners - my Peterson StroboClip HD is the most accurate of them all when tuning in the house where it’s quiet, but too ‘fiddly’ and easily affected by external noise to be any good at gigs, sessions etc.

For gigs, sessions, FCs in pubs etc., my TC Electronics PolyClip and Unitune are by far and away the best in terms of accuracy, visibility, and not being affected by extraneous noises, and those are my go-tos when I’m playing out.

I also have numerous D’Addario and Korg clip-ons, but I find them inferior to the Peterson and TC Electronics tuners, so they live a very quiet life in my desk drawer and rarely see the light of day.

I gave up with Snarks years ago - flimsy and inaccurate.
