Franklin...
First of all..."Welcome aboard!!"

Personally, I play in 2 bands, covering guitars, keys, harmonica, & vocals.
Yes, it can be a little busy at times, but that's the way (uh-huh, uh-huh) I like it.
.."Sorry...couldn't resist the urge to throw that in there"
I bring 2 kbs, 2 guitars, 2 amps, and an anvil case full of all my snakes, cables, mic, etc.
I think Nigel will attest to the fact that it can sometimes get a little hairy, but the end result "the sound" is well worth it, and the $$ split is better than having that extra person on board.

It's really up to you, if you want to do it, no one here can say it's a good or bad thing, it depends on what you're looking to put across for your audience.
...Just my thots..an Good Luck
