A 3 group multi of one in and 3 outs, or single multi-9 outs if you only use the top input, or 1 in 3 out 1 in 6 out if you use the top and middle in, you get the picture. And a little signal adder at the bottom
The build is super easy, barely an inconvenience. Just solder 16 sockets and one power connector and put the front panel on and it’s done.

Good quality, though I did get some noticeable (on the scope) lag between the original slope and the multi’d slope, but I couldn’t hear the lag.

Excellent first kit if you’re just considering DIY module building.
