Ok thanks guys. I'm not worried about my bridge sounding like the Duncan though, and I love the dryness of the Aftermath so I think I'll stick with that, but i'll definitely look into the other suggestions to see if I like them.
My SG had a JB bridge / Jazz neck when I bought it. Replaced them with a ABomb bridge / Mule neck. I have since tried the RR neck on another guitar, which is clearer and more focused than the Mule. From your whish list I think a ABomb bridge / RR neck migh be a good option.
The ABomb bridge is agressive (in a good way), with a low-mid bump that's great for both heavy riffing and lead work, lots of bite in the hi end, and really tight but with present lows (nothing like the JB here). Surprisingly dynamic and clear for a rather hot pup. Oh and yes, it cleans up beautifully with the volume pot for more classic rock (with a modern edge) tones, while still retaining clarity.
The RR neck is quite bright for a neck pup (which I like), punchy, with a vocal, single-coilish quality that I really love.
My 2 cents...
