I've been playing double bass for about 7 years now, all orchestral. I have decided it would benefit me to get a pickup for it to enhance my other styles of play. I checked the sticky at the top with the FAQ, and it was a little overwhelming. I have a budget of $120 or so dollars. The only cabinet i have is an ampeg 4x10 used for my bass guitar. What pickups in my price range offer a good sound for an upright pickup newbie? Thanks a ton, and sorry if this is discussed a lot.
