Stick one of the Artec clones into the bass of your choice?
I had it wired up originally with a single output, but the other pickups just buried it. So, I cut in another hole, made two outputs, and then I run it into an LS2 and I can just stomp it on for extra muddy thunder at my leisure. I actually enjoy it enough that I think I'd like to do it to a MIM Fender P instead of the SX cheapie I've been using (although I've got another one of those Fender cabronita pups coming to replace remaining Jazz, first).
