I was getting a great sound with my Fishman BP-100 pickups mounted on my old Bausch bridge. However, now I've replaced the bridge with a new one, the sound is horrible - thin and tinny. It sounds fine acoustically but the amplified sound is awful. Any ideas why? I checked that the BP-100 was properly installed, and I'm using a Platinum Pro preamp - everything else is set up just the same as it was before. The only clue I have is that the new bridge is quite a bit thicker than the old one - perhaps not passing on its sound to the pickup as effectivelyl? If that's what it is, I'm surprised that it makes such a HUGE difference, and maybe there's an ideal kind of bridge to use for these pickups?
