Never found that with the JB but I do like stuff around 10-14k and paf style works for me too.Oh yeah I agree about the playing part.
I will say that going from a Paf to a higher output can change subtle nuances in one's playing.
I have a Knaggs which had a JB in it which I found quite stiff sounding - I replaced it with a SD 78 and it was much more pleasing in its response etc.
