KORG PHS-1 Effects Unit Phase Vintage Analog Phaser It's in beautiful condition with no noticeable scratches. This item has only been used a few times. I haven't confirmed the operation because I don't have an amplifier. It comes with the original box, instruction manual, and sticker. The box has some stains due to aging. #PHASER ☆I'm also selling other items☆ ↓Please take a look if you'd like↓ #eriinosyumi
