Thank you for viewing. This is the Crews Maniac Sound BUFF OUT. I haven't used it much since I bought it, so this is just my impression, but I think it's in relatively good condition. It's a guitar effects pedal with impedance adjustment and level boost functions, and it's especially compatible with improving the sound quality of digital amps (Kemper). It also comes with a dedicated power adapter (made by Crews). Please consider it. Please refrain from purchasing if you are sensitive to used items. - Model: BUFF OUT - Impedance Adjuster: Yes - Output Level Booster: Yes - Included Accessories: AC Adapter (Free The Tone SP-9) - Power Supply: DC Thru-Out
