I'm from the BG side, but a friend of mine wanted me to put something out there. He is looking for a pickup for his 3/4 Framus upright. He is currently using a Fishman Transducer on it now, and is getting a little feedback from time to time. He runs through the PA strictly, with stage monitors. He wants to keep the Fishman and blend it (via the PA) with a magnetic pickup. He has been looking at the Schaller Magnetic and the Krivo Magnetic. Any input, advice, suggestions?
