A tonewheel organ identical in operation to the legendary B-3, favored by rock and prog pioneers for its rich, overdrivable tone.

Overview

The Hammond C-3 is a tonewheel organ produced by the Hammond Organ Company during the same era as the B-3. Though exact production years for the C-3 model are not definitively documented, the company manufactured tonewheel organs from 1935 to 1975, and the C-3 was in use through the early 1970s. It is technically identical to the B-3 in operation, featuring the same tonewheel sound generation and drawbar synthesis system. The primary difference lies in its cabinet: the C-3 has a more extensive wooden console, giving it a distinct, stately appearance compared to the B-3’s design.

Jon Lord of Deep Purple famously used a C-3, routing it through a Marshall stack to achieve a snarling, overdriven sound that helped define hard rock’s sonic edge. It also appeared in Emerson, Lake & Palmer’s setup during their 1974 Brain Salad Surgery tour. The instrument is described as embodying both the sacred and the secular—the sound of gospel, jazz, and rock excess alike.
