The OS-2 gives you the option to use either overdrive or distortion, and unlike most stompboxes, the OS-2 even enables you to combine both of those effects with the color knob to obtain a blend of unique and harmonically rich sounds. The OS-2 utilizes both overdrive and distortion circuitry which makes this pedal adaptable to any genre of music. The level, tone and drive controls allow you to further shape your tone to achieve the exact sound you want. The distortion of the OS-2 also is able to maintain the subtle nuances of single-coil guitar pickups. If you're looking for a pedal with incredible overdrive and distortion, look no further, this is the perfect pedal for you.

Best first pedal purchase!


I recently visited Sam Ash after wanting to take my guitar playing to the next step. When I visited the store I asked the associate if the Boss SD-1 was in stock. He informed me that the OS-2 was available and that it included a distortion feature. I asked if I could look at the item, and he explained thoroughly how the pedal worked. He never made any condescending conversation like other associates at other music stores have in the past, which I really appreciated. Afterward he guided me to the XLR cables and supplied me with a power cord so I wouldn't have to rely on 9V batteries. I couldn't wait to try it out once I got home and it's worked so well! I will definitely be going back.





Not much difference in distortion.



I recommend it-perfect for a beginner + player


Great product, very easy to use



Boss products are solid and reliable


Boss products are built like tanks, solid and reliable. I like the fact that the foot switches are so quiet there's no audible click when you switch them on or off. I like the OS-2 because I have the option of overdrive or distortion in one pedal as opposed to having to buy two stompboxes. Just trim the setting to your taste and play. It saves precious space on my pedal board. I highly recommend this unit.



Nice, very nice


I'm using it mainly as an overdrive in front of either a DS-2 Turbo Distortion or an MT-2 Metal zone and it sizzles,,, and the distortion on this pedal is not bad ,not bad at all
