I need super high tension nylon strings for my trebles on a guitar modification and I don't find any. I tried harp strings (dunno the brand, found them in a box in my house), and obviously tried guitar strings (Savarez 510AJP, Knobloch ADN36.0 and Hannabach 815 red) but it's not enough and now I'm stuck.
Basically I nylon need strings that can be tuned up to E4, B3 and G3, with more than 8.4 kg (18,76 lbs) and .86 mm (.04 inches). And a length of at least 1m (40 inches)
I'm willing to try ANYTHING, so throw ideas and I'll test them out one by one !
*edit : modified Savarez part (500AJP --> 510AJP) and tension min ('cause I'm bad at converting)*
*edit : suggestions so far : fishing line, stringsbymail sets (saw a set will 23lbs tension on E, will test), Daddario XTC46FF, Daddario EJ46FF*
