Yeh, mini humbuckers. If you are desperate to add the ability to split then you would have to look at some of the alternatives for Hofner pups (they are out there). I think you could also fit the humbucker alternatives for the Rickenbacker toaster pups. (The cavity is big enough but you may have to make new pickup rings) The mini humbuckers that come with the kit sound ok to me, but then I only play through a 25W Rumble.
