I bought this because I tried building my own and failed... or atleast thought I did. While my original one appeared to be toast, I was excited to see this listing. This unit is completely assembled, so no need to worry about soldering skills. Once you receive it, just hook it up with your own wires and power supply, then you're good to go. Since I received mine, I found a fix for the original one I built on the Nsynth Github. It looks like I went from none, to having two now! Haha.
