I've been on enough cramped club/party stages to know that eventually someone will stomp (heavily) on whatever I leave on the stage floor.
In my mind I see the heel of a drunk guest, or fellow band mate even, smash through the LCD, break off the giant chicken head knob etc etc.
There is a reason why stomp boxes are usually made with a simple and solid design
Personally I'm happy to keep my expensive stuff in a rack, while leaving an inexpensive controller on the stage
Well, thats a good point...
But thats why the Floorboard Kemper should be more simple, not having profiler options and stuff like that.
The basics, in a good live ready casing.
There will always be a risk tho, not saying otherwise
