Not me, though. I heard an interview with BB King (some sort of guitarist, apparently) where the interviewer asked him what effects he used. He said that he had tried a wah-wah pedal once and kind of enjoyed it, but decided that it would distract him, and he really needed to just focus on being BB King. We bass players don't tend to be much for effects, anyway. How do you feel about the use of signal modification? Are string and finger dynamics enough?
