An effects pedal with a true bypass circuit, featuring a clean booster and buffer function. - Model Name: WHITE PEDAL - Functions: Clean Booster & Buffer - Circuit: True Bypass Circuit - Series: Master Builder Series - Power: 5V-18V DC I pre-ordered this and waited six months; the serial number is 156. A must-have for those who own multiple guitars. It's delicate, and it's no wonder SHINOS is so popular overseas. I'm selling it because I have a duplicate. Please take good care of it. Thank you for looking.
