Oh boy, if you find the 2nd degree BB bass heavy, you ain't gonna dig the Afwayu.
The Afwayu is a big, thick sounding pu that sounds best in brighter guitars, or guitars that fundamentally don't have a ton of low end.
Killer in an SG for example, or a brighter LP custom with an ebony board.(see Jerry Cantrell )
I feel like the 2nd deg BB is a well balanced, lower output pu, more for classic rock type tones, but I've only used them in Les Pauls.
