My Heritage Custom 575 (based off ES-175) has two pickups with a SOLID CARVED MAPLE top.
I never use the bridge pickup.
When Kenny Burrell was designing his signature Heritage archtop he went with a Solid Spruce top and two humbuckers like his Super 400s. When asked why he wanted the bridge pickup since he never uses it, he said that the extra pup (although never used) help reduce feedback and actually gave the guitar a different tone that he liked.
