Nobody’s figured out what instrument I turned into a fake double-bass with processing tricks in the instrumental recording I posted last week. So here’s a hint – no, wait, two hints:

1. A couple of people have been close, in the sense of being in the right category of instrument. But in each case, they’ve wandered away again by adding on to their initial guess.

2. Directly relevant to clue 1: yes, it sounds bowed. That does not mean the original instrument actually was bowed, and, in fact, it wasn’t. That’s one reason why it’s so amazing. XD

And, of course, from the first post, I repeat:

0. It’s not synthetic, and it’s not a double-bass.

This is a contest, so here’s where you can listen to the tracks, and also the tiny rules list, which is tiny.
