Jeremy's right on! The PG has less bass and like the Seth Lover and Antiquity, that makes it easier for me to get a clearer rythym tone.
Generally, a2 gives a humbucker more mids and softer bass and treble. But the PG uses unbalanced coils which makes the mids more transparent and brighter and the treble a little more extended.
I kind of like alnico 2 HB's like the PG, Seth and Antiquity for the neck position and the 59B or 59TB as a bridge bucker, where the deep bass of the 59B is more appropriate...tho the a2 CC sure works well in my semi hollowbody Monoco.
