MXR released the Limited Edition Wylde Audio Zakk Sabbath Overdrive, model WA44ZS, on June 19, 2026¹. The pedal is a limited edition of the Wylde Audio Overdrive, MXR's overdrive built for Zakk Wylde²³.

MXR says the enclosure carries a special finish inspired by Zakk Sabbath, the tribute band it calls "an homage to the godfathers of heavy metal"²³. Guitar Pedal X describes the finish as a purple sparkle enclosure¹. MXR states the circuit inside is unchanged from the standard Wylde Audio Overdrive²³.

Controls are a footswitch for effect on and bypass, with a red LED indicating on, plus Output for overall effect volume, Tone for overdrive EQ and Gain for overdrive intensity². MXR lists the following specifications²:

The pedal runs on a single 9-volt battery, a 9-volt AC adapter such as the Dunlop ECB003, or an MXR Brick Series power supply². The US list price is $170, available from Jim Dunlop and MXR stockists¹. Guitar Pedal X writes that it believes the units are signed by Zakk Wylde himself¹. MXR's page does not mention signatures³.

Guitar Pedal X describes the release as a limited variant of the regular MXR Wylde Audio Overdrive, which it says is based on the Boss SD-1, and reports that Zakk Wylde has had his own Black Sabbath cover band since 2014¹. MXR's product page states: "Zakk likes to stick it in front of a dirty amp and kick into full-on screaming lead tones with sustain that lasts for days"³.
