Well, I absolutely love it. I have had it as the sole pickup in a p bass and as a bridge pickup with a bisonic in the p position. It has a nice chewy mid-range that can't be beat, in my opinion.
That said, while it is easy to mount, it is very responsive to it's height relative to the strings. This means that while it's easy to mount, because there's no inherent adjustability, you might find you want to increase it decrease it's height without ready made means. I made some shims out of pickguard material I had on hand and depending on whether it was in bridge or neck position found I needed to select different shims to achieve the sound I liked from it.
I absolutely love this pickup and would like to put it in several other basses. In my experience, it has been the best singular pickup addition I have come across.
