This is the Simple IC TDA2030 Complete tone Control Circuit Diagram. This circuit that use IC TDA2030, but this series is equipped with a tone control.
Tone controls include Bass, Treble, and Volume. Power amplifier and
tone control has been put together in a single PCB. This amplifier is a mono amplifier type, can be modify for guitar amplifiers.
If
not coupled amplifier (mic preamp) then you must deactivated
potensio treble and bass, why? because if not using a mic preamp
and still maintain potensio treble and bass sound input (input) from the
guitar will not or the maximum discharge is not tight on the speakers. So you must deactivated a way to decide which directly connected capacitor with the tone control circuit, and capacitor were connected directly to potensio volume and input jack.
