I am not sure how they do it, but apparently Larry and Seymour have figured out to make their crazy output pickups with ceramic magnets have full response and definition. I haven't tried one, but the web site claims the D-Activator-X does that and cleans up when you roll your volume back. I wish I knew that before I soldered that X2N in my guitar.
The rules have obviously changed in the 21st century; ceramic doesn't always mean more output with harsh tone and no bottom end. And Alnico doesn't always mean 'warmer'. Heck, Seymour advertises he uses Alnico 8 now, for crazy output.
Choose your pickup based on the 'other' specs and the sound clips, without putting all your eggs in the Alnico basket. You could be missing out on some great tone.
