Dude. This is very cool and I do believe great minds think alike. I built one as well but I used my circa 2004 cd player and circa 1991 sony dancing led equalizer. I will post pics of it later. I still need to find a small amp so I can actually use the eq. Right now it is just for show. I am thinking about going a little more modern and painting the box white and throwing some splatter paint on it to capture the decade.
