I'm trying to get some opinions on how ceramic magnets compare tonally to A2 and A5 pickup magnets in humbuckers. To my ears A2 has round highs, full mids & slightly rolled off low end. A5s have crisper highs, slightly scooped mids & tighter, slightly bigger low end. How does ceramic compare? I have a pup that's not doing it for me with A2 or A5. I'm looking for full mids, tight & full low end, crips highs and and overall more aggressive sound.
