Bare Knuckle offers them in the active size as a drop in replacement (plus obviously changing out the 25k pots).Your BKP mod makes me rethink that.... lol. Did you have to modify the pickups or do they come in that soapbox size already?
As far as I know, they're the only one offering that soapbar shaped pickup in a metal cover. Everyone else has some variation of the same black plastic cover like the EMGs.
