YAMAHA Chromatic Tuner TD-12, with instruction manual. - Brand: YAMAHA - Model Name: TD-12 - Accessories: Instruction manual, box - Function: Chromatic tuner - Power supply: Battery operated Thank you for viewing. This is the YAMAHA chromatic tuner, TD-12. I purchased this a few years ago for tuning my clarinet, but I am selling it to declutter! The original batteries are still working, so they are still inside. *Please note that the corners of the box are crushed and slightly faded. Please consider purchasing. #YAMAHA #Yamaha #tuner #YAMAHAtuner #YAMAHAtuner #chromatictuner #chromatictunerTD-12 #YAMAHAchromatictunerTD-12
