The following is a circuit of amplifiers are equipped with the appropriate regulatory tone in use to strengthen the electric guitar, using a single-rail supply of about 60V and capacitor-coupling for the speaker . The advantages for a guitar amplifier are the very simple circuitry, even for comparatively high power outputs, and a certain built-in degree of loudspeaker protection, due to capacitor C8, preventing the voltage supply to be conveyed into loudspeakers in case of output transistors' failure.

In all cases where Darlington transistors
are used as the output devices it is essential that the sensing
transistor (Q2) should be in as close thermal contact with the output transistors as possible. Therefore a TO126-case transistor type was chosen for easy bolting on the heatsink, very close to the output pair
R30 must be trimmed in order to measure about half the voltage supply across the positive lead of C7 and ground. A better setting can be done using an oscilloscope, in order to obtain a symmetrical clipping of the output wave form at maximum output power
Note:
To set quiescent current, tide ampare meter in series between supplay with this series, then do the following

- Set the volume control to the minimum and Trimmer R3 to its minimum resistance.
- Power-on the circuit and adjust R3 to read a current drawing of about 30 to 35mA.
- Wait about 15 minutes, watch if the current is varying and readjust if necessary.

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.
