Direct boxes (also known as DIs, which stands for “Direct Inject”) began as a way to resolve a basic impedance mismatch between electro-dynamic guitar pickups (high impedance unbalanced) and sensitive studio electronics (quite low impedance balanced). Still today the primary function of DI boxes is to take an unbalanced, high-impedance signal and convert it to →
