The HB-L came in two versions (around 9k or around 13k)and PAF´s are around 7-8, so the Lawrence pup is a bit "hotter". It´s not easy to describe "tone" but they are different species.
The neckpup HB-R is in the 7-8k area and have a sound on its own. Some people love this pups, some don´t.
To make a long story short, if you are into Page/ACDC/PAF/T-Top land - these are not what you need.
but if you are more into Hendrix/Gilmour kind of tone (when they used Les Pauls) these will do the job.
