Re: Pickup mods & experiments thread
Here's something I came across on pickup magnets and their tonal qualities.
A2 - Huge mids, rounded top, little treble, lots of dynamics, chewy texture, loose low end, low output, very 'vintage'. With the right wind, it's ample mids make a PU sound 'big'. With the wrong wind (or wood) it can sound muddy or flabby.
A3 - Like an A2, but with more treble and lighter on the mids. Mainly suited for the neck slot.
A4 - Balanced EQ, some consider it bland. No big push in treble, mids, or bass. Medium output. Good middle ground for when an A2 is too warm, or an A5 is too bright and scooped. Lets the PU's and wood's natural tones come thru.
A5 - Lots of treble and bass, scooped mids. Sharp high end. Tight low end. Relatively high output. The most common alnico (in it's polished and oriented form).
A8 - Moderate treble, good dose of mids. Firm low end. High output. Could be considered to be a bulked up A4. Suited for the bridge slot. Works in high and low output HB's and P-90's.
A6 - Like an A8, but with less treble. Very rare.
UOA5 - Sounds like a cross between an A2 and A5, with the best of both. Lots of warmth and dynamics, but with a dash of treble and decent output. Another middle ground option between A2's and A5's.
Roughcast - Pitted and lumpy surfaces create a more varied magnetic field. Any roughcast maget has smoother highs, with less harshness. Shifts the EQ slightly downwards. More subtle than an unoriented mag. Usually best in the bridge slot, whereas polished mags work better in the neck (sharper highs).
Unoriented - The internal 'grain' is random (instead of aligned in one direction), making for a complex magnetic field. Highs are softened and tones are more dymanic and 'vintage'. A2's, A3's, and A4's are always unoriented. A5's are almost always oriented.
