So I bought this to set up a multi-chain pedalboard (bass and dual fake-guitar chains, a la Mike Kerr), and it has the room. Plenty of rails for pedals and space for at least 2 power supplies. But when you're done, the thing is simply massive. For now, I've settled on a much simpler pedal setup on a smaller Pedalboard (Classic 2) but I still like having this pedalboard around for when I have another wild idea...
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.
