Silk strings are beautiful for her, it’s true. it is very clear and pure.But could you tell me if it also exists in three nylon string like the classical guitar? What advice would you give me? thank you
Angus, definitely try classical strings or fishing line. Both are acceptable. You have shamisen strings for your current shamisen? Try getting some fishing line or strings and matching up the thickness! 
fishing line… ok, why not ! thanks Kyle !
