I play in a cover band, so I change settings on my bass fairly regularly. We play a wide variety of styles, so I try to make my tone sound as close to the original as possible. For example, we can do a Motown tune, into a tune by the Killers, into a Bob Marley song, into a Blink 182 (yuck

) song, etc...
Sure, I could just dial in a nice, solid tone on my bass (I frequently gig with my Squier VM Jazz) and leave it alone for the entire three sets. But like I said, I try to make it sound as close to the recorded version as possible (including switching from fingerstyle to a pick as need be) - I'm playing the parts pretty much note-for-note, so why not go all the way, right?
Hope this helps...
