Alnico Magnets for Guitar Pickup

by AOMag | post a comment

AOMag have been producing alnico magnets for years. There are several different grades of Alnico Magnets, and the different grades are based on their metallurgical makeup. The most popular for guitar pickups are Alnico 2, 3, and 5; oftentimes referred to as II, III and V. Generally speaking the grades are not in order of “goodness” and the numbers simply denote a particular material composition. Besides what magnet grade is being used, the pickup maker can also vary the amount of magnetic charge (Gauss) the magnet has. Magnets bought in bulk are usually shipped un-charged, and the pickup maker energizes the magnet as part of the build process.

Alnico 2 – Alnico 2 is used most often as a bar magnet material in humbucking pickups. This was the grade used in the early “PAF” pickups, and as a result is commonly employed in vintage-flavored designs. Examples of pickups using Alnico 2 material are the Seymour Duncan Seth Lover, Alnico II Pro, and the Arcane ’57 Experience. Pickups using Alnico 2 material tend to have a slightly soft attack, generally warm tonal characteristics and a slightly loose, bouncy feel. Wound strings have a somewhat woody tone and for some may lack enough definition. While pickups of this sort are generally not wound for high output, when pushed they develop a nice singing quality and make a pretty nice pickup for leads. Players who like to work their amps hard versus using pedals will dig Alnico 2.

Alnico 3 – Alnico 3 magnet material is used in both Gibson humbucker type designs and Fender Telecaster style pickups. Common in early Telecaster bridge pickups, Alnico 3 has good attack qualities, and a clear high end that some would describe as “grainy” and complex. In humbucker pickups, they create a nice balance of warmth, bite and clarity. This is the material used in the Arcane Triple Clone, which is modeled after the 1960 Gibson PAF, and currently my humbucker of choice. Tighter sounding than Alnico 2 pickups, lead tones are crunchy and pleasantly tight, and don’t get overly mushy in the neck position. A nice pick for both rich complex cleans and medium gain rock.

Alnico v – Likely the most popular magnet material, Alnico 5 shows up in both humbucking and single coils designs; Strats, Teles, and P-90’s. Alnico 5 pickups are characterized by strong output, clear tone, and punchy attack. This all sounds pretty good, and just about every conventionally constructed Stratocaster pickup uses Alnico 5. Some of most popular humbuckers use Alnico 5 including the Seymour Duncan SH-1 (my second favorite), Duncan JB, and just about every Rio Grande pickup. Compared to Alnico 3 they may lack a little sonic complexity, but for those about to rock, Alnico 5 is a very good choice.
