I started out many years ago with a Korg WT12 as you could use it for acoustic instruments as well as plug in a guitar or bass.

When the Intellitouch came out, I jumped on the "clip on" bandwagon and used that on guitars and basses for many years. Then a few Black Fridays ago, the Snark came on sale for under $10 and I bought several, some for me, some for family and friends. Not sure why rockstar_not had problems with his but all mine work great.

Next I came across a capo from China that had a built-in tuner, and for $20 I figured I'd give it a try. Been using it ever since.

Finally (another Black Friday sale) I picked up a few d'Addario minis https://www.sweetwater.com/store/detail/NSMicroClip2PK

They're small and unobtrusive and I leave one permanently attached to both my banjo and my ukulele.
