I bought it for a Boss TU-3 to drive other pedals, but unfortunately it's not the best design. The cable between two plugs is not long enough if one pedal has a socket on the side and the other on the top. So you have to leave out one of the plugs, and instead of 7 pedals, you can only use it for 5 pedals. Another disadvantage is that the plug is not L-shaped, so if there are pedals in several rows, it can get in the way, break the top row, etc.
