Great high gain overdrive/distortion. Based on the Friedman BE-OD, this pedal only costs a fraction of the price of that pedal. Sounds almost identical, just check some of the videos online. Mostly metal case, but with some flimsy plasticky parts in some areas, which withdraws a star. Though it seems sturdy enough. If it ever breaks I'll buy another one, or maybe even the Friedman, because the sound of this pedal rocks. Does it chug? Yes, it certainly does!
