Anyone ever heard of Mosstone jazz bass pickups

[Aaron D]

So I have this 1993 made in Mexico Fender jazz bass,it's the best jazz bass I've ever played,I added the fender hi mass bridge to it and a brass nut. I also used a green scratchy pad and removed the clear coat from the bass,giving it a matte finish,anyway because of boredom one day I decided to research this bass to find out why it sounds so good,so I Google what stock pickups come in a 1993 mexican standard....the answer came back as Mosstone pickups,so my question is anyone else ever heard of mosstone ? NOT MOJOTONE,MOSSTONE. I've tried looking for a website but couldn't find none. Being a part fender used,you'd think they'd have other products,which is what I'm curious about....I also discovered that 90s fender jazzes came with 2 neck pickups as apposed to a neck and bridge..anyone ever heard this before?
