SD SA-1 Blackout hum...

[vector]

Got a H/S configured ax that has the SD Blackout AHB-1 in the bridge and an AS-1 in the neck but the AS-1 hums noticeably when 3-way selector's in the middle and neck position and the strings aren't "deadened" I'm guessing it's a grounding issue but don't know for sure. Anyone have an issue like this?
Solutions?

New guitar or did you put them in?

Single coils are always noisier than Humbuckers. But if you have a nasty hum it's probably a ground issue.

Does it go away when you touch the strings? (is that what you mean by deadened?) If so then it is almost defiantely a gnd issue.
