MXR ZW-44 WYLDE OD The ZW in the name does refer to one Zakk Wylde, who you might recall from his work with Ozzy Osbourne or Black Label Society. His leads are not for the faint of heart, and his sound, well, think unrelenting crunch. Now you too can jack up your sound with the Berserker Overdrive. You might think distortion, but no, this pedal is more for taking your amp to the next level sonically. Oh sure, it will give you a dirty sound if that’s what you’re after, but get your amp to be all it can be by clicking on this gem. You’ll give your amp more sustain without coloration, allowing it to flourish.
