Probably because he doesn't know any better. If you work and work at it, you can find one decent setting on it. I'm not saying this because I'm some sort of Boss hater or pedal snob - I owned one for a while. I got fed up with the finicky nature of the ODB-3 so I went looking at other options. I sold it immediately after I plugged into an Ampeg Scrambler. I don't play bass in a band anymore, but you should have seen how wide my bassist's eyes got when I showed him what the Scrambler sounds like on bass.
