Carvin has radiused pickups that Brian Bromberg worked with them on. I do not know if they sell them aftermarket. I have seen a pair on the used market, but I do not know if Carvin only sent him news ones because he had a Carvin bass. I have no clue what those shapes are, so I do not know if they are the fit you are looking for. I have a pair, and I do enjoy them but they are a little to perfect, no real character to them. I suppose that could be the Carvin pre-amp too.
