Yes, KISS works everywhere.

I acknowledge everyones stage step up can be unique depending on the venue and level of investment. From carrying an acostic on stage to coming three hours early to run cable, it all depends on what you intend to deliver.

I long ago had to decide if I wanted to be a musician or a technician when it comes to gear. In my case no roadies availabel to carry the load and no soundmen to handle the PA and mixers. My set up is simple and has been optimized to focus on what I can provide musically.

So the decision is yours. How much gear does your show really need? That is the quetion you need to answer.
