I'm a very very satisfied Quarter Pound user, so I won't be switching... I'm just wondering what the tonal differences are between the Quarter Pound and the DiMarzio Model P. According to the DiMarzio website, the Model P offers "Heavy sound with midrange emphasis. Aggressive sound designed to cut through dense tracks and loud situations." They also go on to say "Model P pickups cut through the band without sacrificing bottom-end power. Gutsy mid-range provides growl when the bass is pushed hard. Combine the DiMarzio Model P with a bridge position DiMarzio Model J and experience any tone from a tight mid-range punch to a warm bottom-end with bright, clear attack." That, to my ears, is exactly what the QP sounds like. Any thoughts? Comparisons?
