These pups are a collaboration with Lindy Fralin Pickups. We make the components here in Maryland and Fralin Pickups winds them in Richmond, VA. While they are a cosmetic match to the original Bill Lawrence designed Micro Frets pickups the windings and gauge are different. For that reason we only sell them as a pair for optimal balance and tone. Please note the original Micro Frets factory were always changing things up therefore some extra routing of the pickup cavity could be possible. Pickup mounting holes will line up with no problem. Since they are made to order for you expect 3-4 week delivery. Any questions feel free to reach out via email. Free shipping in the continental US!
