Do clip on tuners work for electric guitars?
Clip on tuners can be used to measure and display pitch on acoustic or electric guitars by simply clipping on the headstock's vibration.
Are clip on guitar tuners accurate?
These tuners can be fairly accurate, though cheaper clip-on tuners aren't as good in loud and noisy environments. This is because the neck will pick up vibrations from other instruments, like bass and drums. But for ease-of-use, it doesn't get much better.
