I'm not sure yet. It leaves me with only 1 pickup. You can use the sustainer itself as a pickup but it's configured to sound like a single coil which is not very useful on this guitar. I've read on the sustainiac website that it can be configured as a humbucker so I emailed Schecter but they said they never use humbucker config for the sustainiac. With that said, the EMG 57 sounds amazing and you can use the Sustainiac to create sounds you'd defo not be able to without it.
