Looking for Active Pickup

Currently I have a Fishman passive pickup (no battery?) in my Kamaka Tenor and I would like to switch over to a active pickup. Does anyone know where I can find one online, maybe a Fishman? Or if anyone has any other recommendations, it would be great appreciated!

Thanks,
Rod

Check with MGM. He might not have them online but I'm pretty sure he has them in his shop. I know for sure he has the MiSi pickups.

Thanks for the info Ronnie! I have just got done reading some reviews on the Misi and Mike does have them available. I think I may give it a try. Has anyone put one in the Kamaka tenor yet?

Thanks Again!
Rod
