Well, drop tune metal axe is a LP type (though more in the ESP style) and I got a Stockholm in the bridge and a Supermassive in the neck. The reason I did not go for the pair was that while I really wanted the power, fatness, and agression in the bridge, which the Stockholm delivers in an amazing raw style (brilliant modern rock and metal PU), in the neck I wanted to take a step back. When a talked to BKP they described the neck differences as the Stockholm being more heavy on the bass and hotter than the Supermassive. Since I do not like super fat necks I went SM.
Really great neck PU. Distinctly modern with proper modern cleans, that amazing P90 definition, and warmth. Still a rather fat PU on the low strings for my personal taste, but still quite allright since it is so defined and clear in true P90 fashion. This does not get mushy easily if at all. I have played riffs and stuff on it by accident more often and longer than I care to admit. For leads it is brilliant. The P90 attack makes it amazing for fast playing. Seperated yet fluid.
