here is a 2015 version of my Marshall speaker mod which will be backlit to hopefully add a glow to the logos, knobs and striping around the boxes. It would be mounted in the pros similar to where the LE's have theirs. The photo is a 2013 version in a AP members game.

latest - the quality of the multicolour 3d printed plastic was crap in colours and a more flexible plastic and subject to warping - samples were throw aways unfortunately.
