I had a small board for ages and squeezed in a big box Cali76 and a basswitch so didn’t have much room for anything else. It was a great lesson in restraint and ergonomics.
My current board is bigger but so long as things are placed ergonomically and my FOH signal path (no switching required) and the pedals I need to get quick access to all fit in I’m less worried about the look. Function over form.
