The DiMarzio DP159 Evolution bridge pickup is a hefty humbucker designed for maximum impact and power.  The Evolution pickup's sound is tight, aggressive, and loud.  It incorporates DiMarzio's patented dual-resonance coil configuration that senses more harmonic overtones than ordinary humbuckers.  Perfect for solos that really cut through.  Low notes are very tight, and the highs have a lot of presence.  DiMarzio designed the DP159 pickup for Steve's Ibanez Jems, but it can add a lot of punch and definition to Les Paul and similar set-neck guitars - even the lowest bass notes really jump out of the amp, and feedback occurs easily with a wide range of harmonic overtones.
