Guitar amplifier electronics are often split into two worlds: vacuum tubes (the classic "warm" sound) and solid-state (transistors). Both follow the same basic signal path, but use different components to achieve gain. Conclusion

• Voltage (V): The electrical "pressure" that pushes electrons. In a guitar amp, voltages range from millivolts (at the input jack) to over 400 volts DC on the plates of power tubes.
• Current (I): The flow rate of electrons. High current is needed for the speaker output stage.
• Resistance (R): Opposition to current flow. Resistors set bias points and control gain.

Conclusion

• Introductory electronics textbooks on amplifiers, tube amp-specific guides, and manufacturer service manuals are recommended for deeper study.
