Sometimes, while the rest of the band is setting up, I'll groove along with whatever is playing on the stereo. On new years eve, an old school Run-DMC tune was playing on the house system. So for fun, I turned on the compressor, cranked up the highs and started "scratching" on the bass. All I did was rub my fingers back-and-forth against the strings. But, it made a convincing "scratching" sound like a DJ spinning wax. I had a lot of fun with it and really getting into it. I looked up and noticed people in the audience were watching me, and when the song was over a couple of people were applauding. I don't know if others have done this, but it was cool to find a new sound for my palette that the audience could get a kick out of.
