NPD: EMG SA-7 7-string Single Coil (FINALLY!!!) - Sevenstring.org
JRRshop.com : EMG SA7 Single Coil Pickup for 7-string guitar [sa7] - $89.00USD
Wow, I'm actually surprised they haven't gotten on this a little bit sooner.
I really like the SA's for 6'ers. They're some of my favorite singles for 6 string guitars.
