"I've been buying from zZounds for almost 10 years now and they treat me right. If you have a problem they always have a solution. They are also very knowledgeable about the products they sell."

With classic guitar stompboxes like the Mu-Tron, HAZ Laboratories gives guitarists that characteristic envelope filter sound. It's like a wah pedal on steroids. Call our Gear Experts now for help with your purchase: 800-460-8089.
