Hi Lee, that pickup on the Queen B is just one of the standard cheap Chinese single coil pickups. it sounds fine to me, but I am not very picky. If I don't like the way it sounds, I just adjust my modelling amp to make it sound better.
But it works just fine. Since it is a CBG, I don't think folks should be expecting it to sound like a Les Paul with humbuckers in it. It sounds like what I think a CBG should sound like. :-)
