Hello I want to add sound to the saber I am currently building. I just was curious, does the Pre-wired PC board come ready to go once installed in a saber? Where does the SD card come into play or is it even included or necessary? The board does work with the buckpuck and all other MWS parts doesn't it? Sorry guys I don't have much spare time with all the hours at work I'm getting all of a sudden so I don't have much time to read through the soundboard manual. Any help would be great! Thank you so much!
