Overview

Combining their flagship distortion and overdrive pedals into one box the Boss OS-2 allows you to blend a parallel signal between a distortion and an overdrive for a complex variety of tones. This pedal is great for adding some clarity to your lead tone by blending in some overdrive, or add girth to your rhythm by thickening up your tone with some underlaying distortion.

    Verified Purchase

    This pedal doesn't get the credit that it deserves. I replaced my fuzz pedal with this. The fuzz/distortion is great. Good note definition and slick harmonics.

On the overdrive setting with the gain set low you get a won…
