DiMarzio Evo 2 Bridge Humbucker Pickup - Black Same as the original Evo 2 with more headroom and dynamics It kills on 10 and cleans up when the volume is rolled down With a little less power than the original Evo 2 it balances perfectly with the Evolutio neck model and performs equally well with high gain and vintage amps The original Evolution bridge guitar pickup did exactly what Steve Vai wanted it to do: kick butt and produce serious scream The Evo 2 DP215 bridge pickup was designed to be more complex -- the same basic tone with increased headroom and dynamics, so that the sound kills on 10 and cleans up when the volume is rolled down
