Don't waste your time asking Bare Knuckle for advice !!
As you've already discovered they are useless.
I wasted so much money being wrongly advised by them that I'll never use their pickups again.
With regards to your control layout is there a reason you want 2 volumes ?
What pot values are you using ?
I'd advise a 250k master volume, 250k tone for mid and neck and a 500k tone ( with 0.015 cap ) for the bridge.
You'll need a super switch to do it.
That'll give you the best chance of getting the tone the pickups can give you.
