I picked up a new amp a few months ago, and I decided to try running two amps together. After a bit of research, this pedal seemed to be the best and most economical way to accomplish this. As I expected, I experience a bit of signal loss, but it is so insignificant that I really don't notice it. As a bonus, I realized that there are a lot of very cool things I can do by selecting one amp at a time as well. I have not run it with 2 in and one out, but I assume it would run well in that configuration as well.
