I want to know the answer to the following question:
What other instrument did the Tennessee string bands use?
All the background I'm provided with is that "Howard Armstrong, who is famous for blues violin, got his start with his father's mandolin and played in string bands similar to the other Tennessee string bands he came into contact with, with band makeup including "mandolins and fiddles and guitars and banjos.". Is that enough to answer the question?
Answer: no
