Following the renaming of the dual pickup Broadcaster, production and promotion of the single pickup Esquire was briefly discontinued. It was reintroduced with a truss rod in January 1951. The only external differences between these second generation Esquires and the Broadcasters and Telecasters of 1951 are the lack of a neck pickup, and the "Esquire" label on the head. Although the Esquire had only a single pickup, it retained the three-way switch of the two-pickup guitars. This switch modified the tone of the pickup by making it bassier in the forward position, while enabling use of the tone control knob in the middle position. With the switch in the rear position, these tone controls were bypassed entirely for a "hotter" lead tone.
