I bought two Buddies for permanent connection to the FX pedals on the Radial KL-8. One is connected to the send output, the other to the receive input via the Buddy's "output," which can be either an input or an output, depending on what you want. It works great, and now all my effects units can be connected at once and stay that way. I haven't experienced any crosstalk between channels, which I've experienced several times with the Franklin Audio SS-6 MK1, for example. The switch is made of flimsy plastic, so I'm deducting one star, and I'll look for something more solid, but otherwise it's all solid metal. It can be labeled perfectly with a label maker and 9 mm tape so that I can see which FX unit is connected to each channel.
