Hey all. I've been playing bass for more than a year and my bass still has on its original strings. I'm thinking it's about time to change them because its been a while. But i know nothing about strings. I have a sammick bass (its a cheapo until i save up for my fender), i play in a classic rock band but i love to slap. I have four strings. I guess i want low action because its easier for slapping? but not too low because i do finger style the majority of the time. So what strings can you reccommend for me? Also, my band has a gig in one week. Do i change strings before the gig or do i wait until after the gig? For all you string experts, please help me out! Thanks!
