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.
