It's always a good day when we hear of a new pedal from Z Vex! The new Double Rock was initially make as a one-off for J Mascis of um.... what's that band? Dinosaur Jr! It's two Box Of Rock pedals in one box, but with some tweaking. Now you can adjust the sub frequencies like on the Distortron and you can convert each channel into their super popular Super Hard On boost. This gives you a few different ways to cascade overdrives/distortion. Sweet!
