It all depends on the type of music you play and what you want from the pickup and of course the person playing it! Low output pickups will always have a cleaner more open tone with less compression. A miracle man with an alnico V mag (DC17.6K) and a Nailbomb neck (DC10.2K) are as high as we go with neck pickups.
This is all really useful info for a clueless person such as myself -- I hope this kinda thing goes into a FAQ update somewhere! :)
Definitely
not being a shredder dude, and wanting to keep those "more open, less compressed" tones in the neck pup, I'm thinking I'll want to preserve in my eventual BKPs the kind of "bridge about double the neck" output balance that exists between my stock pickups now (and so put in a relatively hot bridge, too).
Now I'm really keen to see how the Abraxas, particularly the neck, turns out. Ah, well, waiting is good for me!
