I am in search of the lovely double bass thump sound and am going to buy a hollowbody... but I'm pretty sure that the cheap Chinese Harley Benton stock strings that will be on the bass will be terrible. I'm looking for some nice medium scale or longer strings to put on that will have a great, deep low-end with that nice thump, and I'm pretty sure that flatwounds have this type of sound. I would also like them to be pretty "loose" strings that don't feel super tensioned when plucking for a better feel. Any suggestions on specific sets? Thanks - I know nothing about strings.
