I was shopping for a PedalBoard and everything on the market was not what I was looking for or WAY to expensive. I saw a "wall corner" on my Balcony and realized that by fitting them in a "L" configuration it would be perfect for my needs and I could do it the size I wanted.
Step 1: The Rick-Rack
I think the images speak for themselves, 2 pieces of "wall corner" galvanized metal with 4 locking bolts. cut two Equal pieces of 5 inches for the sides And Voila!
It cost me $25 Canadian. Anyone who saw a PedalBoard before will understand. PedalBoard on the Market can be VERY expensive and rarely customizable.
