I put one in an eighties ESP mirage, bolt-on, ebony fretboard and a non-recessed floating bridge. I have no reference point with that guitar, but I do have a Custom with the same magnet in a neck-through Soloist. The FS is tighter, sure, and has less low end. Both have great note separation and retain clarity even with the big magnet. Maybe the FS is a little clearer.
I swapped the Custom+ to a Black Winter the other day and I can say the BW is higher output and middier, but less clear and definitely more extreme. The Custom is just the perfect pickup
