ST-2 Tuner : 10 years and still going strong!

I've been using the same Snark tuner for the past 10 years. It does a great job. Display is visible (best with fresh batteries), responds quickly and exactly to the notes you're playing.

I've tried cheaper options, including from the 'house brand' of this store. Those just tend tend to get me angry, since they make the simple process of tuning very annoying. I strongly suggest not skimping and just getting the Snark, the difference is not that much at this price point anyways.

Durable as well ... the only issue I've had with mine is one of the rubber pads came off, but you can get it back on, no problem. I got myself a couple of these as backups, but the original one I had just keeps going.

Without a doubt, one of the best investments I've made as a guitar player.
