Selling to organize my equipment. Used only at home. This is an MXR envelope filter for bass. It's a 15th-anniversary model. As the name "blackout edition" suggests, it's all black, unlike the original. The LED is orange. The DRY (original sound) and FX (effect sound) controls are independent, allowing for settings that won't lose the low-end feel of the bass. There's a scratch on the bottom, but otherwise, there are no noticeable scratches. #Effecter #Bass #Guitar #MXR #M82 #Autowah
