Hello, 
My first post here, but i'm frequent reader of this forum. So, i came to you asking for a little help. 
I bougth a dimarzio at1 (at least adversited as) in a platform like craiglist but in portugal called olx. Used and the seller adversited that with was a at1. 
I received today and there's no place in the pickup that says dimarzio. Is this normal? I'm no expert, but i think it's a two conductor. Is this possible? 
Thanks in advance
