I was just reading the previous thread and it started to wander into the subject of the Barbera. I've used the BP 100, Underwood, Wilson, Realist, PUTW, DYN B, Stat B, Mics and I've tried a bunch of the other offerings too, oh and the Barbera. I would rate the Barbera as way up there in Piezo sound. It still has the piezo whine but with 8 elements in the bridge it picks up in a very even and controlled way. I dont think the sound is so fantastic as to overcome its problems though. When a Barbera goes bad, it drags your whole bass with it. I had a Barbera that after a while one PU element began to fuzz. I know I could have sent it back but I don't really have two bridges that I keep going for my bass (thats why I have adjusters) so I would have either had to have a new one cut, or take a vacation for several weeks. I noticed that when I finally had a new bridge cut that I had been nursing the old shape thru fingerboard work that made it less then an ideal playing shape but because it was unalterable I just dealt with it. Mine now sits on a shelf with other expensive useless relics. I have to say tho.. to show up with the barbera plugged into anything and just one thin wire coming off the bass was nice. I never had feedback anywhere and the evenness of the tone was very nice. I have been using the Pick up the World for some months now (sounds like a clearer and more mic like Realist) and I just bought a full circle (i have been interested in this pick up for a while- someone told me it sounds best on dark toned instruments like mine) I've never heard the Barbera sound woody though. It was a nice PU to blend with a mic.
