Out of curiousity, I recently spent a few minutes with a neck-through Thunderbird at the MI shop. I really liked the general feel, workmanship, dimensions etc of this bass. The only thing I did not really like was the tone of the pick-ups - humbucker is not my thing. I have found reference to SD SSB-4 but have not found any good sound clips. I play mostly blues, rock and a bit jazz/funk: 98% fingerstyle and 2% slap - no pick. (Typically, the Thunderbirds seem to be played exclusively at knee cap height by pick wielding rockers, which makes it hard to find reviews applicable to my styles. ) The sound I am looking for is single coil Jazz. For my use, I REALLY liked the SD design pickups in the Squier CV Jazz. I do not want active pickups or preamp.
