I have a Custom Custom that I found lacked bass/low-mids, and a lot of people in this forum advised me to change the Alnico 2 magnet to a Alnico 8 Magnet. And boy were they right! It added exactly the right amount of bass/low-mids, slightly reduced the high-mids that were abundant while making the highs more prominent for them to almost scream each note while never having the dreaded ice-picks. Now my bridge pickup can chug any heavy rhythm and scream any solo my fingers can play... It's a very aggressive, full sounding, balanced, distortion loving bridge pickup for any type of Hard Rock & Metal out there!
