No offense to all of us guitar snobs on the forum(myself towards the top of the list), but the average person in an audience doesn't give a shit what your amp or anything on stage looks like. (As long as the lighting is cool, and the bass drum has a custom head on it with the band name, and the mic stand has a long bandana on it) They are just there to have some fun and listen to some hopefully good music and appreciate good sound quality.
Now me personally, i examine pedal boards, amps, check settings from in front of stage, But that being said, I'd also be way intrigued by an "amp less" stage set-up and probably want to ask a lot of questions.
