My very humble pedalboard. This is a homemade version made of 6mm x 50mm pine slats. It was initially made with the cheap wood because this was a test build. It worked out pretty well so I am using it. As for sturdiness... I don't think it will break unless I really try. I specifically made two layers so that the back layer is slightly higher than the front. This makes it harder to accidentally step on the front pedals.
