The YAMAHA TDM-700 is a convenient musical instrument accessory that combines tuner and metronome functions. I've thrown away the box, so it's not available. I've confirmed it works, and it functions without any problems. If you'd like, you can also purchase the stand for the tuner together. - Brand: YAMAHA - Model Name: TDM-700 - Functions: Tuner, Metronome - Volume Control: With volume control function - Tempo Range: 40-208 BPM Thank you for looking.
