This is a pre-amp guitar circuit suitable for high impedance type electric guitar pickups. The circuit is based on a uA 741 op-amp (IC1). The IC1 is wired as a non-inverting amplifier. Resistor Variable R1 can be used as a volume controller. Resistor Variable R6 can be used as tone controller. The switch S1 is used to produce “brilliant” or “soft” tonal effects.

Description Op-Amp UA741
The UA741 is a high performance monolithic operational amplifier constructed on a single silicon chip. It is intented for a wide range of analog applications.
* Summing amplifier
* Voltage follower
* Active filter
* Function generator
The high gain and wide range of operating voltages provide superior performances in integrator, summing amplifier and general feedback applications. The internal compensation network (6dB/ octave) insures stability in closed loop circuits.
