Hey everybody! This probably been asked so many times before, but i seem not to find it, sorry! i Have a MIA Jazz Bass with Badass bridge II on it, i'm looking to have super low action, as low as i can get, even if i have a little bit of a fret buzz. I worked on the saddles, and on the rod, still not low enough, should i shim the neck? Will it be a better setup for a low action? Should i use playing cards, or a credit card? Thanks for all the input!
