SB2 Passive Summing Mixer Kit

Great little box.

I've made passive summing boxes in the past, but this one is by far the most pleasant experience I've had. It's easy to use, small, and offers 16 channels. What I love most about this type of summing box is that I can pair it with other simple gear like zener diodes or germanium diodes to get even more saturation and color, on top of the preamp of my choosing. I wish we could buy a rackable unit with a bazillion channels, but maybe that's not feasible. Either way, this is a great box. If you're lacking I/O, pairing this with an Arturia Audiofuse X8 OUT is a cheat code for the price.

This thing is wild. Took like 30 minites to assemble (and I’m not great at assembling things). The sense of openness and depth was big enough that my wife who doesnt care about mixing at all could hear the difference

Works great, perfect for beginners!

Really cool and inexpensive entry into soldering and analogue summing. I couldn’t be happier!
