Thank you for looking. Operation confirmed. I believe it can be used without any problems. The TM-60, a multi-functional tuner and metronome, supports accurate pitch adjustment and rhythm practice. As this is a used item and has been stored at home, there are scratches, yellowing, and missing parts. Please check the photos. Thank you for your understanding. *Batteries are not included. - Model Name: TM-60 - Functions: Tuner/Metronome - Power Source: AAA batteries - Tempo Range: 40-208 BPM
