I love dual 490 combo in my SG and I don't want to change them. I've played with a bunch of SDs. like sh4, 5, 6, 13 and 2 and 59 in neck - in LP. SDs are great but there is some qualities in 490s that fits my taste. This is not the matter of gain and output in nowadays amps and boosts which can give you massive gain from quite low output pickup. For me it's better to have lower output since it gives some clarity - but maybe it's just my years. Played an LP with 498 in the bridge and it was too compressed .
