You should have learned knot-fishing before you got that knot. Don’t know what that is? It’s easy. You need a needle and a knot.
1.Pick up the needle
2.Insert the needle into the loop that the know consists of (don’t rip your response)
3.Now your knot should not longer be in the gap
4.Every knot is a puzzle, take a good look at it to solve it
5.Now your string should be free from knots
Note that with more complicated knots, you may need to fish out several loops. If so, repeat step 2 and three. If your knot consists of too many loops, it might be tricky/impossible to get the knot out. But if you have a knot from dropping a triangle, it should be enough to fish out one loop. I have no idea if someone else have thought of this before or if it’s my idea (if so, it’s copyrighted). My idea or not, it will work.
And when it comes to the Jamboo, I have gotten the impression that it’s more of a collectible. And I’ve also heard it consists of many individual parts, therefore a pain to reassemble. It is playable, and will probably have longer sleeptime than a stock Duncan Butterfly, just don’t expect to get God in a box.
