Tube Amplifiers
blakelydakota asked:

Im trying to find out that a little more about how the guitar amps and it works so that the semi-conductor transistors use of amps in contrast with the pipes but I need more specifics and the mat are completely wrong about the transistors. Someone meets me all right !!!!!!!!

    The key is the pickup on the guitar. It uses an internal magnet and coil for each string. The vibrating string changes the reluctance of the magnetic circuit and so it changes the magnetic field as the string vibrates. This changing field produces a voltage of each string. The voltages are added in the pickup to produce a voltage signal.

    All the amp does is to amplify the voltage and provide some current capability to drive the speakers. Many modern guitar amps would use analog integrated circuit amplifiers in the input stages and then discrete power transistors in the output stage.

    Maybe this will help some…
