I love this little tuner. Not expensive and does the job. Don' t buy the Snark , reviews say they break too easily. This Samson looks a lot like a fishman I've seen. So this one is good for Guitar,Bass,Violin,and Ukulele. Nice read-out (LCD) and changes color to indicate TUNED. It also has an ON-OFF switch and a multi-angle display, comes with the battery.....go get one !!
