Bill Lawrence Pickups are cheaper than a seymour duncan, when you buy a Bill Lawrence pickup you talk DIRECTLY to either Bill Or Becky, both are very friendly. And the invader is used by blink 182 where as the l-500 is used by Dimebag from pantera yeh i just threw the last fact in for fun. Thats why i prefer a bill alwrence. And Seymour Duncan must think the L-500 is good too, i mean they made their own lame copy that only cost twice as much and sound worse... and dime still uses the bill lawrence l-500 not the "Dimebucker".
