The buddy effector from Limestone Audio offers a variety of effects. This is an analog delay. You can adjust the output volume, making it useful for boosting volume during leads. I purchased it new and used it for about six months, but I'm selling it because I've started transitioning from an analog board to digital. - Model Name: buddy - Color: White - Manufacturer: Limestone Audio - Included Items: Original box - Number of Knobs: 4 - Switch Type: Footswitch Thank you for looking.
