Radio Design Labs ( http://www.rdlnet.com/ ) has a series of incredibly small yet high quality (low noise to signal ratio, etc) units for very specific utilities, such as splitting and switching and converting from Hi to Low impedance, etc, etc.
I think they were called the "stick on series." But I'm not sure what they have now, it was years ago, but worth checking into for anyone trying to keep a small footprint (which most loopers do because we tend to do a lot.)
The units themselves are about the size of two matchbooks and you wire them in yourself. The power supply is bigger so if you find yourself getting a few, get the power supply that powers a few too.
Creating a signal flow design with these things back when I put 5 instruments and vocals (with 2 sets of affects) into 3 echoplexes was super fun and worked well.
I may still have some to sell if you get interested. Not sure which ones, but I'm quite sure I have a splitter or two left.
