Single-pickup guitars have a certain something about them. They force you to find ways to do more with less. They have fewer pickups pulling on the strings at all times. They have a certain stripped-down cool. But another thing I like about single-pickup guitars is that they often have a trick or two up their sleeves. Take an Esquire, which has no business having a pickup selector switch. But flip it to one side and you have have warmed, filtered goodness. Flip it to the other and you may have a direct, unfiltered sound that out-Esquires itself. What hidden tricks do you have/like in a single-pickup guitar? I want to hear it all. Coil tapping, different caps, kill switches, afterburners, the works.
