KORG AUTO CHROMATIC TUNER AT-12 This is the Korg Auto Chromatic Tuner AT-12. Years ago, Shigeru Naruse introduced this product, and although it was a bit expensive for a high school student like me, I worked hard and bought it new. It's an old item, but it has few scratches and stains, and it works without any problems, so it's in good condition. I was able to confirm the operation in all switch positions. *Operation was confirmed using both the included power adapter and batteries. The tuner needle illumination also lights up properly. It's been so long ago that my memory is vague, but I think almost all the accessories are included. I recommend it to those who enjoy a retro feel or have a special attachment to this tuner. 　Instant purchase is available. 　No price reduction. Recently, there seems to be an increase in troubles related to returns. Please understand that this item is non-claim and non-return before purchasing. Thank you for viewing.
