I'll be following this with interest - need to do the same thing myself now I'm back from the US; will probably need some advice now I can string it all together.
Chris, if you, Steve, or anyone else have any questions, as the self-appointed forum pedalboard expert I would be happy to grace your screen with my wizdom.
Cool Stevie! My one and only tip is that as your board is like my Keeley which is just angled but flat, I made some spacer blocks and stuck Velcro top and bottom to raise the front end of the second tier. Makes using the pedals at the back a lot easier.
