The KORG clip-on tuner AW-2G is compatible with guitars and basses and features a compact and lightweight design. It works without any problems. Purchased new several years ago. I think there aren't many noticeable scratches or stains, please check the images. If you are concerned about small scratches on the LCD screen, please peel off the LCD film. The box is also in good condition. It has not been used in a pet or smoking environment. I will clean it lightly before shipping. Please read my profile before asking questions. - Brand: KORG - Model: AW-2G - Type: Clip-on tuner - Compatible instruments: Guitar, bass guitar, mandolin, ukulele - Size: 58mm(W) x 48mm(D) x 16mm(H) - Weight: 19g Thank you for viewing. #HelloKitty #GuitarTuner #BassTuner #ElectricGuitar #HELLOKITT #KORG
