The Blues Driver BD-2 offers a wide range of sounds, with adjustable level and gain. - Model: Blues Driver BD-2 - Color: Blue - Knob Types: LEVEL, GAIN Thank you for viewing. This is a listing for the effector unit and an AC adapter. The paint is chipped in places, showing signs of use, but it hasn't been used frequently and is in good condition. I have confirmed that it works properly when connected to the AC adapter. The check lamp also lights up correctly. You can check the operation by plugging a jack into the INPUT side, so please prepare one to test it upon arrival. Manufacturer: BOSS Type: Electric Guitar
