An option to buying strings is to buy fishing line. Below (on my instagram) you will find which string strengths to use for the G C E and A strings. I will update with the sound video of it soon.
Here are some links to go buy some Ukulele strings if you’d like.
A String (30lbs tension)
E String (50lbs tension)
C String (60lbs tension)
G String (40lbs tension)
This is what the new fishing strings sound like.
