I bought this but didn't use it, so it's a new, unopened item for sale. This is a KYSER quick-change capo for acoustic guitars, compatible with 6-string guitars. Although it says "for acoustic," it can also be used on electric guitars. - Brand: KYSER - Model: K6G - Type: Acoustic guitar capo - Feature: Quick-change function - Compatible instruments: 6-string guitar Thank you for looking.
