I had the opportunity to meet Jerry Calder from PedalPods at Summer NAMM 2019. I was walking by a booth and saw a big SUV driving over a gray box and immediately wanted to find out what was going on.
Turns out these are boxes that can be interconnected to form the pedalboard of your dreams. There are tons of technical benefits of having these pods and personally felt they are very affordable for what they do.
