Re: Duncan Custom series magnet swaps
From A2 to A5 to ceramic the output gets stronger, the attack increases and the resonant frequency increases.
While highly unpopular in this community, I would be suspicious of any claims of stronger bass relative to the mids. In all likelihood, these will only be anecdotal and qualitative assessments that will not be backed either by solid theory or by measurement.
I'll happily defer to people who are well versed in the science of pickups.
