I recently purchased a 1977 BC Rich Eagle bass for next to nothing. The possible reasoning behind the low price being the previous owner had taken out the original Dimarzio DP122 cream coloured pickups, cored out some wood, added filler and put these pickups in. I'd have asked the previous owner why he did this, but I bought this thing on consignment. This thing plays like a dream, the pickups cut through nicely in the mix. I wish this had the original pickups but I'm not hating these ones. Does anyone have any idea what these are? Which make? etc... I'm just trying to wrap my head around why someone would swap the originals in such a drastic way.
