The Radial Q3 Coil EQ is an induction coil equalizer designed for the Radial Workhorse and other 500-series racks. It features 3 bands for passive, induction coil equalization, taking after Pultec and Manley EQ designs. The three bands are for Low Boost, Mid Cut, and High Boost. A fourth control is for makeup gain, and there are EQ in and high-pass filter switches. The three bands each feature 12 position Grayhill switches (including an off position). The Q3 also features an effects loop insert point, allowing use of the Omniport feature of the Workhorse. With this feature, you can insert processors directly into the EQ signal chain.
