I regularly play considerably larger gigs than that with sounds that only have a subtle delay and a bit of reverb.
Bigger gigs doesn‘t mean you need bigger fx chains - at all
Most gigs I played In my life I played without any kind of fx.
With a dual rectifier or a steavens poundcake.
0 fx on the stage besides a wah.
But I never dare to say this here..until now..😆
