The bass player that influences me the most currently is Justin Chancellor of Tool. He always plays interesting stuff, his sound is half of what makes Tool be what it is, he loves to experiment with effects and he always plays whats relevant - never to much and never to little. There are many bas splayers that are good to great but Justin is one of those people that I find has some real uniqueness to him. I can't say the same for some other people who have fantastic technique but really doesnt push their playing towards something special.
