I'm selling this because I bought a BD-2w. It's great for creating sharp, cutting sounds, and also works very well as a booster. Operation has been confirmed (◯). There's no crackling. Body only. The BOSS Blues Driver BD-2 is the perfect effector for blues sounds. - Model Name: Blues Driver BD-2 - Brand: BOSS - Number of Knobs: 3 - Color: Blue - Country of Manufacture: Malaysia Thank you for looking.
