Here the schematic diagram of simple pre-amplifier for electric guitar:
A pre-amplifier circuit suitable for high impedance type electric guitar pickups is given here.The circuit is based on a uA 741 op-amp (IC1).The IC1 is wired as a non-inverting amplifier.The POT R1 can be used as a volume controller.The POT R6 can be used as tone controller.The switch S1 is used to produce “brilliant” or “soft” tonal effects.
- Assemble the circuit on a good quality PCB or common board.
- The amplifier can be powered from a 12V battery or 12V DC power supply.
- Up to 24 V DC can be used to power the circuit. 12 V DC power supply is recommended.
- The IC 1 should be mounted on an IC base .
