![]() ![]() When being used as a switch, a transistor can allow a small current to pass through one part and turn it into a much larger current. In a guitar circuit, this is essentially boosting the signal to produce a much larger output volume. ![]() When a transistor is being used as an amplifier, it takes a small electric current at one end produces a much larger electrical current at the other. However, some lower gain pedals may make use of field-effect transistors (FETs) HOW DO TRANSISTORS WORK? These semiconductors generally contain three pins and for building guitar effects pedals, we’ll generally be using bipolar junction transistors (BJT’s). Transistors are active components for our circuits and we use them to amplify or switch our signal. ![]()
