The first thing we need to do is find a way to mount the LED's so that they can be positioned in the best place possible. To get really bright results we will need to mound 8 (eight) LED's inside the Shure 55 shell, this means that there will be four in each corner front & back.
Looking at how the microphone cartridge is mounted, the best way is to make a frame that can be bolted on top of the existing structure. Firstly measure the mounting holes distance from each other and determine how much space you can take up without touching the mic cartridge.
The best way is to use a thick piece of cardboard as a template, you can trim it as you go to ensure it fits perfectly.
note: we take no responsibility for you damaging your microphone in any way shape for form! Mod at your own risk!
