I had a similar thread going on in the Strings forum. Was just happy with the BP-100 - sounded great, no issues. Of course my teach (who was a BP diehard) just said to me last week, "Hey I stopped using the BP and now only do a realist for the past year or so. I want to hear a realist on your bass". Well ok... so I find a nice one thanks to another TBDBer. After futzing with a fallen soundpost, I get the pickup installed. What? I couldn't believe my ears. I thought the BP was great on my carved Cleve... the realist KILLS it. ***? Played through Pro-Plat EQ->Focus SA->Wizzy 10. At low volumes, it was transparent - the kind of transparent like I couldn't tell the amp was on. Had to turn the volume down to know that the amp was working. Reminded me of when I played through the PBJ Flightcase without the upfiring speakers. At higher volumes it was blissful. EQ-wise, I had to actually cut the mid ranges just to get a natural sound. The pickup's output is very hot for me. Yay - now I can go back to using the big ol rubber mute much easier. Just goes to show if your'e serious about this stuff, you really do need a drawer full of pickups that goes right next to the drawer full of strings - just to get the right match for the bass. Gets rather expensive. So far the Cleve works best (in order of preference): Realist BP100 Ehrlund Full Circle Go figure.
