Different Magnet Types and Sound Info
Alnico 2 - Warmer sounding with less magnetic pull to allow the strings to vibrate more freely. A good choice for warming up a bright or harsh sounding amp and guitar. Overall the Alnico 2 is warm, with clear mids, spongier bass, and a softer attack. Many players use the Alnico 2's to better achieve the vintage tone heard in many pickups from the 50's era.
Alnico 3 - Considered to be brighter than Alnico 2 with the least magnetic pull to allow the strings to vibrate more freely. A good choice for clean tones and lots of articulation. Overall the Alnico 3 is bright, with clear mids, warm bass, and a softer attack.
Alnico 4 -This magnet is best described to have the characteristics of both Alnico 2 and Alnico 5. Kind of a happy medium.
Alnico 5 -Bright sounding with more focus and enhanced dynamics. A good choice for adding a brighter punch to a warm or dull sounding amp or guitar.
Alnico 5 - Short -Providing more focus in the upper-mids and brighter highs. The bottom-end is deep but very controlled and coupled with the extra cut in the high-end. Great for organic, clean and driven tones.
Overall the Alnico 5 is bright and punchy, with glassy highs, tight bass, and more attack. Alnico 5 magnets are the most commonly used magnets in guitar pickups today.
