We used that classic jazz tone foundation and added some punch. These pickups are voiced a little lower than a traditional jazz, with a hotter output and fuller low end than the original, giving you boom without too much top end sizzle. The hand ground alnico 5 rod magnets, and custom coil wind deliver a warmer, fatter Jazz Bass tone with a lower midrange growl. The more aggressive attack from these pickups make them great for all things rock.
