I've have a DellArte Hommage with a DellArte Bigtone and I've also put on a Dupont Bigtone that I purchase here on another guitar. The thing I notice that was different about the construction was the DellArte element seemed to be installed by slicing the top of the bridge off and installing in the middle. The Dupont element seemed to be epoxied into the bottom of the bridge. I no longer have the Dupont BT, but my memory is that it sounded warmer than the DellArte BT. Perhaps this is because it's in the epoxy and further from the strings. I also assumed the elements were different, but Alain Cola sent me an email saying he was the person who referred Dupont to the German maker of the piezo element--so they both use the same element according to him. There's a big price difference, so I'm wondering if my experience of sound difference is typical or not. Any opinions? Does anyone know exactly who the German maker of the element is and their contact info? I have a new guitar and need a new pickup, but if they are the exact same element/pickup, I'd rather not pay $110 more for a Dupont BT since they are already quite expensive. But if there's a legitimate difference, I would consider getting the Dupont.
