IMO.....First gig with that setup I would DEFINITELY take an amp. If you don't know about your PA set up you will be at the mercy of whatever is available. If there's not a dedicated foldback wedge for you you may not be able to hear yourself and no amount of tone tweaking on a pedal will fix that.
I recently did a similar gig - was interstate and was invited to sit in on a 3 set covers gig. I had my bass but no amp. I was basically playing off what I could hear from FoH and would have killed for even a small combo.
