I've seen a couple of people do this before but never saw an explination on how they did it, and obviously some companies offer it as an option for their pedalboards. I'm having the underbody of my Pedaltrain Pro fitted for lighting. The pedaltrain is coming in the mail. Here's how i'm doing it.
2 12' Dual Cold Cathode Lights (I opted for blue)
Some Zip Ties
1 4 Pin Molex Y Adapter (You can get the one with the lights in the connectors and sexy UV reactive mesh)
1 AC 110v to DC 4 Pin Molex Converter
Sticky stuff or velcro (i'd go for velcro)
The materials cost around 30 bucks. Here's what i've got on it so far:
My cathodes and Y Adapter came in today so i'm planning how to put them on the pedalboard. I'll cascade them and velcro the blue boxes to the side, then the on/off switches will go against the backside of the pedalboard. The Y Adapter will meet in the middle with the AC to DC converter, in the mail BTW, and velcro to the backside of the pedalboard. I'll use a 3 outlet adapter velcro'ed to the back of the board attatched to an extension cord to power both the board and lights from there.
Sounds alot more complicated than it is. All of the slack cable will be ziptied for neatness and should be very clean. Here's a floor layout of what i have on it so far.
As it progresses, i'll update. Yay.
