One of the more obvious choices for boards. Perfect for the 'just want a board, don't wanna spend weeks in workshop' crew. Has space for decent number of boxes, pedals and power. Would benefit from some built in cable routing underneath but I guess they've left this to enable full customisation. See my euipboard for my layout.
As a guitar player fascinated by pedals and the effect they can have on guitar tone, the Pedaltrain 3 offered me a large palette to play with as it offers a large surface area for pedals meaning that I can have an extensive selection of pedals at my feet during a performance but not so big that I get lost when looking for an individual pedal. In other words, it is amazing in that it offers the size of the Pedaltrain 2, but not the difficulty that comes with transporting a large pedalboard.
