I play guitar, bass, mandolin, square and round neck resonator and a little banjo. Acoustic/folk/bluegrass/blues/Americana type stuff. These cheap Snark brand clip-on tuners are famous for falling apart. This one has been fixed twice and failed again. I have upgraded and bought a Peterson and several Fishman's, but I just had to do it...
It's become a challenge now to make it indestructible.
