This low cost bass treble circuit consists of some capacitors, resistors, and two T/C pot for BASS and TREBLE control. this circuit can be made without even a veroboard. You just solder components as this circuit network is not so complex. It has only two-pin parts.
Let’s take a look at he circuit diagram. Nothing to say about it, as it is so simple that a beginner level hobbyist can even understand and build this circuit. But there are some -ve points of this circuit which I must say, after giving you the circuit.
- As no external power supply, the O/P power is much lesser than I/P power, so volume decreases.
- The treble control doesn’t act as linear, it increases treble a lot in the end pot side
