The SS has a very clear sound, with a nice crisp attack. It doesn't overdrive the amp like other
high output pickups like the tone zone. It works just fine for going chugga chugga though. I guess its not as ballsy as a really high
output pickup, but then again the moment I try to play something besides powerchords I get fed up with other pickups.
In my RG760 when I turn the volume down the bass sort of drops out on the SS and it gets a very trebly, twangy sound. Makes me think of Warren Zevon's Lawyers Guns and Money.
It sounds really boring clean. I switch to the middle or neck.
Edit: I like the comparison with a single coil. The only pickups I can stand in the bridge now are the SS or a single coil, but I don't like what happens with the SC pickups I have when the gain goes up or you pick hard.
