Easy-to-use clip tuner SYC-01, with instruction manual. - Model: SYC-01 - Brand: Syain - Type: Clip tuner - Included items: Instruction manual ※Batteries not included. Used a few times and then stored at home. Power on has been confirmed. (Operational check not possible as I don't have a guitar) The main unit is clean, but the outer box and instruction manual have noticeable damage such as folds. Thank you for looking.
