Only Bill Lawrence Pickups (Classic) pickups featured a curved blade, others are flat. I am looking for info on when this change was made (I'm guessing somewhere mid to late 1983, not long after the "Bill Lawrence USA" imprint appeared). Current By Bill Lawrence (WS) pickups feature wider blades than current Bill Lawrence Products (EZ) pickups.

• 1979 - The original Bill Lawrence Pickups (Classic) pickups featured curved 2.150inches long blades. (pictured right)
• 1983 Changed to thinner flat blades, 2.150inches long. (after the appearance of the BILL LAWRENCE USA Imprint)
• 1984 - present Bill Lawrence Products (EZ) 2.150inches long.
• 1984 - present By Bill Lawrence (WS) 2.225inch blades. These blades are also wider.
