Re: Neck pickup Compatible with SD Tapped Custom bridge pickup (Esquire)
if it's the pickup I think it is -- alnico 2 @ 9+K/ ~6K tapped, then there's a "matching" custom shop neck pickup. I think the specs are alnico 5 @ 7.5-8K.
I have this set in a couple of teles with 5 way switching, and they're my favorite set.
I'd suggest contacting MJ, she'll know exactly what you need.
