My stock Gibsons have great low end but are real muddy and adjusting heigth only helps a little. I play blues and blues rock, so a thick yet articulate and expressive sound is what I am going after. The low end would be nice since the SG has less mahogany than a LP Special and having low end for a warm tone is a good thing. I was thinking of Lollars, I know they are not as aggresive, but generally great P90s. Are there any other Lollar winds I could get? Are there any other brands of P90s that work particularly well in SGs?
