Anyone ever use these. I was curious about them since I couldn't find much info on them. Im prolly gonna go with bartolini's or maybe bill Lawrence...but Im not adverse to saving some cash. http://www.azguitarparts.com/index.php?main_page=product_info&products_id=89 Are these epoxy sealed pups rails underneath, for those who might know? Ive emailed them and didn't get a response.
