This is a convenient model "STH200P" made by SEIKO (Seiko) that combines metronome and tuner functions into one. It is a new, unused item. I purchased it but never had the opportunity to use it, so it has been stored unused. The high-volume design makes it ideal for practice with large groups, such as brass bands and ensembles. It can be attached to a music stand, providing excellent visibility and operability during practice. The pink color is easy to see and makes it easy to identify your belongings.
