Born out of necessity in studios such as motown and united sound systems to accommodate the electric instruments emerging in the 1960s direct boxes also known as dis which stands for direct inject began as a way to resolve a basic impedance mismatch between electrodynamic guitar pickups and sensitive studio electronics.
