Absolutely. At 1-5 it adds a dynamic that is awesome. A thickish crunch. The middle is around 16k as opposed to the bridge and neck at around 8k. It's badass man. Period.

Most dudes replaced the bridge pickups for hotter models which most like Duncans came open coil. If you liked the neck, no reason to replace it. Voilà...
