Electric guitar has been a very popular instrument with
modern teenagers. Its usefulness and variety of sound is greatly enhanced with
use of electronic effect units. The simplest and most economical in the list of
such devices are the various units that alter the tonal quality of sound emanated
from the guitar. The bass booster described here, when used in conjunction with
a good quality medium impedance pick up and medium priced guitar would produce
the bassy sound often found on huge bass guitars. The circuit diagram given in
Figure 6 shows that it is a straight forward direct coupled amplifier with
feedback applied from collector to

base of each transistor.This feedback applied through capacitors C4 and C5 is
frequency selective by nature. The impedance of the capacitors decreases with
increasing frequency which means less amplifier gain. As a result higher
frequencies are attenuated more in this amplifier as. Compared to low
frequencies. The value of capacitors C4 and C5 can be any thing between. 001
Mfd to .05 Mfd but both of these should be of the same value . using a larger
capacitor for these would give more of bass boost. If desired, different
capacitors may be switched in for varying degrees of bass boost. Resistor R1 is
a simple level control.
