You clamp it to your guitars head-stock, turn it on... and it just works! Works by both vibration and microphone. Mine stopped working via vibration. I emailed the awesome people about it at Snark and before I knew it, I had a brand new replacement sent via mail! Love Snark!
Great for Home Use
Dead on accurate, durable, and helpful- as long as you're not on stage. It's nice to tune off of vibration rather than sound in a loud room, but almost any show is too loud to get a good read with one of these. I'll stick to a pedal tuner. Great gift for any musician.
Affordable, accurate and responsive
One of the best clip tuner at this price point. The red model offers vibration and mic modes. Only issue is that the rubber piece on the grip falls off after some time. I would recommend an updated version of this tuner. Display is much clearer and improvements to the grip
