Just to answer some questions I've had on the item:
The pickups are the factory stock EMG-HZ's which are passive.
The pre-amp is an active EMG BQC system which has been wired for 18v operation but can be changed to 9v, I've also included in the sale the original 9v Spector tone-pump pre-amp.
Any more comments or questions, please either send me a message or write it on the post.
Cheers,
Phil
