Just curious how common this may be ... to start playing the song with your digits, and at some point in the tune whip out the plectrum, or vice versa?? If so, I would think it would be of benefit to have some type of pedal with at least two amp presets, unless your technique is really refined, no? Any popular (or not) songs I might hear some bassist doing so? I'm sure it's been done, and I probably already have heard it before ... I'm just drawing a blank and it's got me curious.
