A typical guitar / bass tuner recognizes the instrument-specific tones E, A, D, G, H, E, while the chromatic tuner is able to recognize all twelve tones of the western music concept. Clip tuners work with vibration sensors that pick up the vibrations where they are most intensely transmitted in guitar, bass and many other plucked instruments, but at the same time are also easiest to measure, namely on the headstock. The big advantage is that the ambient noise is not perceived.
