I am looking for a versatile, yet "slappy" 4-string, and am interested in both of these models. I used to own a Thumb 5 and loved the tone. However, I couldn't cope with the neck diving. So now I'm thinking Streamer -- but which one? The Jazzman has a J/MM pickup configuration, while the Pro-M has a unique setup: a double jazz pu in the Music Man position, with separate preamp for each half of the pickup. Your thoughts?
