So I've got this old plywood bass that does me pretty well. And about a year ago, I saw a good deal on a realist, so I picked that up. I've played in combos and big bands with this setup, and it's been satisfactory. What I'd like to do is start playing my upright in my rock quartet. The problem is, some of our songs are really dang loud, and when I turn myself up loud enough to match my band, the realist feeds back like crazy. (The amp i'm using is an SWR super redhead with a Goliath III extension cab) Which leads me to my question: what is the ideal pickup for playing very loud pizzicato?
