它是80年中期的名器Bill Lawernce的L-500 XL,以前 Washborn Nuno N4和 Pantera Dime用的那一顆, 聲音屬乾乾麻麻的, 穿透力很強, 基本上SH-13想模仿L-500XL的音色, 但完全不像, 而Seymour Duncan的SH13是Dime幫忙代言的...不過不要被騙囉,他只是把名字賣給Seymour Duncan而且.他還是在用Bill Lawernce的Pickup.
請參考: The L-500 is a blade-style humbucker that can be retrofitted in both full-size humbucker and P-90/P-100 routs (see Dimensions post below)! The blades are 56mm/2.205" long, and will accommodate the string spacing of all known 6-string bridges (remember that the bridge pickup is not mounted at the saddles!). L-500's are designed to deliver as much output passively whilst maintaining clarity and without sterility. If even higher output is required, EMG active pickups are recommended. To deliver great tonal flexibility, the lead/bridge versions (L & XL) especially are recommended to be used in conjunction with the Q-Filter. The L-500 comes in four versions: C = 2.8 Henry R = 4.8 Henry L = 6.8 Henry XL = 9.2 Henry The XL requires at least 500K pots, whereas the other 500s can be used with 250K or 500K pots (all audio taper). All 500's are extremely loud and therefore don't really mix well with other pickups. The XL without the load of the controls is ear-piercingly bright, but with a 500 kilo ohm pot loses about 50 percent of the higher end. With the EQ Filter [(Q-Filter)], you can gradually [effectively] reduce the inductance of the XL and get a tremendous variety of sounds. The L with 250K pots is tonally voiced very similarly to the XL with 500K pots, but theres not quite as much punch? And if you employ a Q-Filter, theres not as much bandwidth to operate on, which means that the tonal variation that can be achieved is not as extensive as for the XL.
