Ajish4, grab some old 'The Archers' albums and hear what slapping can do in a church setting! I have played guitar for 39 years but about 30 years ago I heard a funk band here in Portland at Up the Down Staircase and they had a bass player on a BC Rich Eagle that blew me away. I started also playing bass after seeing him play (I also purchased a 1979 BC Rich Koa Mockingbird new).
Having said that, I really don't like to solo much for the simple reason that I don't think the audience gives a rip (drums stop, very bad! Time for bass solo). Also, I'd rather play a guitar solo, but that's my own thing. Holding down the groove is an art in itself, and took me a number of years to begin to appreciate it. I'll play slap, thumb, normal, pick, fingerpicking style, anything that sounds good to me and not worry about it.
