Small passive mixer for Monotribe, Volca etc

I made some small 4 channel passive mixers, great for small tabletop set-ups, 4 mono channels, built using good parts, the size is a little smaller than a iPhone, each channel has a level control and there is a master level control. Nice and simple and clean, always a handy thing to have around, price is £30 plus postage.
