I recorded a transformer with a guitar pickup then broadcasted it from a speaker, then re-recorded this sound, waving my mic at the speaker (like a light sabre). Add a bit of chorus and voila, it's that light sabre sound. Could be a bit more beefy, you can add some sub or something, anyhows, hope some of yous get some use out of it anyways innit???!.
