This MXR ZW-44 Wylde Overdrive is in good condition and is in fine working order.
Get the famous Black Label Society/Ozzy Osbourne tone in a single guitar pedal. The ZW44 OD replicates the recognizable heavy, chunky tone that Zakk is known for. Use it in front of a clean signal for a nice consistent OD, or with an already dirty tone for screaming leads.
