I'm seriously considering putting the Basslines MM-style alnico pickup on a custom with the 3-band Tone Circuit w/slap contour they designed to go with. I'm hoping it's a very robust, aggressive sounding pickup that has all 3 tone ranges, brick-solid lows/thick mids/articulate highs. A guy at Seymour Duncan said even Flea would be proud of them. Any opinions on these or even the ceramic models? Thanks for any info, including where you got yours. (BTW, a search for this pickup really only turned up people who said they had them, not much on how they sound).
