Wilkinson pickups anyone?

Anyone ever try one of these? The specs read that it's rated at 13.9K ohms, which suggests that it's a fairly hot pickup. But I can't seem to find any data on the inductance of the pickup, or the output in millivolts, which would tell the whole story. I sent Wilkinson an email but I've yet to hear a reply. Since the DiMarzio X2N-7 is rated the same in terms of resistance, I am wondering if the Wilkinson might be close. But DiMarzio also provides the output in millivolts, which is 510 mv. So I am at a loss. The reviews all say it's a great pickup, but I just want to know if it's hot. Any ideas?

Never heard of em.
