Re: Using an effect Gizmo on the pedalboard?
Have a look at this:http://www.pedalgear.net/page20/page20.html
I asked a similar question and Ron said that it can be done. I have decided to go mini rack instead and keep the stage footprint small, but I think this would be a great project (I may still build one in the future).
I was going to build mine with just one surface elevated to allow the EG to mount in the back with the control panel facing the audience. I didn't get past scale drawings but basically it was going to be 18x32 inches with 1/2 inch ply frame and an opaque polycarbonate top. This would allow room for the power supply and Mini Line Mixer beside the EG under the top with all the guitar and amp I/O on the back panel too.
Just do it!
