Hi guys, I am about to build a new guitar to replace my current one as my primary instrument and have some time to think about my pickup selection while the neck gets built.  I have heard great things about BKP and am open to trying new things if I think it would be a step up.  
I currently use a Lundgren M which, to be honest, I have no serious complaints with.  The tightness and low end are superb and the overall tone and output nice, but I would like some more sizzle.  If I could find a pickup that had the tight punch and low end of a Lundgren M with a nastier sound I would definitely be interested.  Does BKP have anything that might fit that bill or should I just continue with my tone tweaking?  I should add that I do not do any leads, what-so-ever, so I don't care about how the lead tone sounds.
Thanks in advance!
