I have a US-20 and presently drive an Axon AX-50 and a WP-20. It works great, lets you run one or the other or both. I paid $250.00 for it but in the long run it's been worth it because it works and it lets me do what I wanted to do. The other device from Germany that I think you're referring to is a SW41 by Klaus Schock ( http://www.klausschock.com/Products/products.html ) It's designed to use up to 4 different guitars going out to one 13 pin device. He doesn't make them on a regular basis, I ordered one last year about this time and only just now recieved it, but haven't had time to play with it yet. Oh, and the price of that is 215.00 eur. Recently I've been experimenting with a breakout box and running each string into bidule and processing them individually. Got some interesting results, but boy was that a drain on the cpu! Of course if you have enough stomp boxes you could do the same thing with hardware and then bring each signal into a mixer. I tried to use the US-20 with the breakout box but for some reason the switching doesn't work and you always have the signal from the BOB on but I could turn the synth side on and off.
