If you are going to go with BareKnuckle pickups, you need to match them to your gutiar(woods) and to your rig.
I have a Nailbomb/coldSweat combo in my all Mahogany Carvin DC727 (maple top) and they sounds killer in that guitar
thru my peavery 6505+.
I have a Miracle Man in my ibanez 7620 bridge and that sounds killer as well, but completely different from the Nailbomb
thru my Mesa Mark III.
the Miracle Man works great in a basswood guitar.
The Coldsweat neck pickup is probably just the best all around 7 string neck pickup out on the market.
