Thanks, again. I realize that trying to theoretically recreate the tone of a PUP by matching a few aspects is futile. One variation can completely change the tone. Mainly, I'd be interested in a softer jazz "bop", rather than a country "snap". I get the impression that the L610 would provide more of a "bop".

The only discrepancy I see is your magnet descriptions. It states otherwise in this post: http://guitarsbyfender.yu...ill-s-main-contributions

It doesn't say what softcore is, but hardcore is steel, and Alnico is...Alnico. Therefore, the L609's are Hi Q steel, and the L610's are? I don't actually care which magnet is used, as long as I get a PUP with the attack characteristics I want. One type must provide a softer attack than the other. They can't be the same, right?
