YAMAHA TDM-75 (Original price: ¥7,000) This unit has tuner, metronome, and recording functions. I used it about 7 years ago, and it seems this model is no longer in production. The "TUNER ON" and "METRONOME ON" buttons require a slightly firmer press to respond. I have checked all other functions, and they work without any problems. Please understand that it has been stored at home. Thank you very much. #YAMAHA #Tuner #WindBand #Music
