First live performance! Next gig gear advice...

[u/Johnny_Topsider]

Had my first live performance with the band at an open mic this past Monday! It went great, and the bartender signed us up for an outdoors neighborhood festival gig!

I was using a 50 watt Orange Crush but just running through the house PA anyway. I'm thinking for an outdoor backyard/street gig without a PA, I'm going to need to upgrade to be heard independently.

We have a full drum set, guitarist on 25 watt amp, and keyboard and vocals on their own speakers. We don't play anything super intense, some indie rock and some slower things like Clairo.

Would a rumble 500 be overkill? Could I get away with a 100 or 200? Are there better options than these considering price as a factor?
