Great piece of equipment. I'm using this pedalboard with a Line 6 HX FX and it BARELY fits, I must apply a bit of force to close the case. Measure everything if you plan on using taller pedals. The board also has lots of space underneath, I could fit a power supply and 2 DI boxes there. Rockboard also makes patch bays for these, but I don't recommend them. The one I got had noisy jack inputs, so I just affix my inputs and outputs with zipties on the opening in the back of the board.
