I know I am going to ask some "loaded" questions here but, I've been thinking about band to play a few gigs at bars and clubs in the area. How much income can one roughly expect from a gig? Should a band invest in a PA and sound guy? When playing these small rooms should a rig concentrate on tone or versatility? Should a keyboardist invest in an amp or just a nice DI? Any general recomendations? Thanks.
