This thread reminds me of when I had a small lap harp made for me in Oz about 15 years ago. I even travelled down south to try out the maker's harps before ordering mine.

When mine arrived the nylon strings were so hard they reminded me of tennis racquet strings. They were difficult to pluck and the sound was lifeless. I immediately sent off to a string company in the US and bought the same beautiful strings I have on the larger harp. The difference was amazing.

So, unless the weedwhacker string is soft and pliable, I wouldn't recommend using it to make music with. LOL
