Ting

I have four strings bass , My tuning is E 100, A 65, D 020p,  g. 020p, I saw a “9 strings bass “on YouTube, it should have some strings thinner than 020p , that’s why I want to buy a pack of “9 string bass” strings , so I have more choices to change my setting

Where can I buy 9 strings bass strings ? Thanks 

Hi, Are there any individual bass pickups for each strings? I used a submarine pickup for G string and D string . But the pickup was broken last week😔 Can anyone give me some suggestions? Sorry my english is not very good .

Thank you
