I had a similar thing as OP — Nano board, wanted modulation, had to have top jacks, prefer easy interface — but the UK I had didn't last long. I was mostly using the chorus, and the sound just didn't do it for me. Moved it for a CE-2w, which sounds amazing but I'm also not in love with, so I'm guessing I just don't love playing with chorus and am now on the hunt for something else.
