When its me alone Ive always used the bassline from 'Goodnight though' by the wonderstuff, one of the first basslines I learned, it grooves, uses a decent range and I like it, I also like the fact that i still use it lol. I also do some high register stuff with harmonics, just to make sure they understand im not just a 'dum dum' bass player, and that i like the whole register of my bass to be heard, then i go through each effect like guitards do, so they also know im using 'em, they never ask!
The whole band normally play the first song in the set and then a verse/chorus of anything extra needed, such as more keys or extra bv's.
