Re: magnets
Swiped from a simliar thread over on the Hamer board a few minutes ago.
"Ceramics are the strongest, and the AlNiCos as commonly used rank, in order of descending strength, A5, A2, A3.
All else equal, the stronger the magnet, the higher the output and the stronger the low lows and high highs. So ceramics will be brighter and stronger than the rest, and A2 will be softer and seemingly have more midrange - because they have attenuated highs and lows.
Most humbuckers use a 'standard' magnet size, same as Gibson used in humbuckers and P90s. Super high output humbuckers occasionally have three ceramics, though - the X2N, Invader, and Gibson 500T are like this."
