The type of magnet could / should reveal itself by the bass response ( depending on how firm or spongy the guitar's intrinsic tone is of course ). Also the character of the very top end . If AII Stormy, they will be clear enough, but relatively 'soft' - and if moving up to a Mule, tight enough to Riff- yet still warm. AV and the VHII / Riff Raff category, tight'n'bright e.t.c. :)
