Thank you for viewing. As the title says, I am selling Kikutani GM-ST3 guitar tuners. The following is a description: The GM-ST3 is compatible with 6-in-line tuners for electric and acoustic guitars. High-quality materials and a sturdy construction provide reliability that can withstand long-term use. ・Versatile design: Compatible with many steel-string guitars, including classical and acoustic guitars. ・High-precision tuning: Achieves smooth and accurate tuning, improving pitch stability during performance. ・Durability: High-quality materials and a sturdy construction provide reliability that can withstand long-term use. The reason for the "new, with a defect" status is that I purchased it new from a musical instrument store, but it seems that the store may have been planning to sell them individually. If you check the image, you can see that "550 yen each" is written in magic marker. (The 550 yen part is blacked out) However, after purchasing it, I never opened it from the bag, and it has come to this listing. (Originally, I was going to use it for a self-made guitar, but that plan was thwarted) I think it's a great deal for those considering a new purchase. (The lowest price on online shopping at the moment is 3106 yen on Rakuten) Thank you for your consideration.
