The EMG BTC System is the full installation kit version of the BTC two-band active EQ, packaged with all of the wiring components needed to fit the module into an active EMG system. The kit contains the bass and treble pots, the EQ circuit board, the solderless quick-connect harness, the output jack and the battery connector configured for use with EMG's active and X-Series pickup ranges. A single 9V battery powers the entire chain. The Active and X wiring presupposes that the pickups feeding the EQ are EMG active or X-Series designs. Players running passive HZ pickups should look at the BTC-HZ System sibling, which carries the load resistor network HZ pickups need. The System version saves the player or builder from sourcing the wiring kit separately, dropping straight into a guitar set up for an EMG quick-connect harness. Best suited to a full rewire of an active EMG-equipped guitar where two-band shelving is the right level of EQ for the build and the player wants the complete chain in one box. Pairs naturally with active and X-Series humbucker, single-coil and dual-mode pickup sets across the EMG guitar range. Two-band bass and treble EQ; complete installation kit included.
