Sorry to bring up this summing stuff again.

I'm curious. Has anyone attempted to build their own summing bus? The ones on the market (Dangerous 2b, Manley, Folcrum) are pricey. If you can build one for a $30 bucks why not try it. Below are some links for DIY summing mixers. I can solder a cable but Idon't know squat about building a circuit.

The following link is too this studio in germany who builds a lot of his own outboard gear. He built a beautiful 32 channel summing mixer. No schemitics but it's soo perty. He seems to feel it helped his mixes also.
