Hi,
just wanted to spupport the statement that 490s aren't Soapbars. What works for Bill's PUs will notalways work for other PUs. As I understand it with Bill's offerings inductivity correlates with output and "darkness". But I read that P-90s have an inductance of as much as 8 Henries. But they are NOT louder or darker than Gibsons humbuckers (around 5H?).
So inductance is worth as much of little as DC resistance when it comes to comparing PUs of different brands/conctruction.

By the way: has anyone tried a q-filter on a P-90?
