D'Addario Piezo Tuning Clip, PW-PTC-01
Turn your sound activated tuner into a vibration based one with this useful device. The PTC-01 clips to a vibrating part (bridge or headstock) of an acoustic instrument with or without electronics. The ¼” plug goes directly into your tuner allowing vibration based tuning. In noisy settings, your tuning capabilities will be dramatically improved. You will also find that tuning accuracy overall is usually better with vibration based tuning.
