Looking for tone Control using 4558 opamp

That is very well spotted 🙂 The pins look reversed, it should be inverting, as are all these type of stages.

Any common opamp can be used, TL072, 4558, TL082, OPA2134 etc with no change needed to any other parts.
 
yeah tnx a lot, your a big help for me, i forgot if it is using single or split power supply, i will check it again later, but can i use any of those two power supplies? so it should be inverting, right? tnx again for that, can i also ask if what kind of capacitors will i have to use? if it is polyester or ceramic. i apologize if i had a lot of questions, hehe
 
Caps 1uf and under that are in the signal chain should be film or polyester type. ry to avoid ceramics for those in the audio path. Anything over 1uf and you are looking at electrolytics (unless you believe in using very large bulky and expensive alternatives).

polyester is a type of film cap, the prefered film caps are polypropylene (PP) or polystyrene (PS) or polyphenylene sulfide (PPS) or teflon (PTFE) for best linearity, polyester is slightly inferior to these, but not hugely bad.

Ceramic caps that are not NP0/C0G are not linear or stable and have no place in a filter circuit signal path, use only for decoupling. The NP0/C0G types are perfectly good though.

Electrolytics do not have stable values and should be avoided for filter circuits if at all possible.
 
Right then... it won't work. The configuration is all wrong. The first opamp will produce absolutely no audio output because the input (via the 10k) is feeding into a 'virtual ground' which appears as a short circuit to audio.

The same applies to second opamp. It can not work.

Even if you correct those two errors, the response of the circuit will be unusable I suspect.

so what to do in order to get output signal

It needs a total rework. As it stands (after a simple modification) you can only configure it to reduce HF, not boost bass.

Even the input coupling cap is the wrong way around. It is a disaster.

This will give a gain of '1' and you could then add caps to reduce HF but not to actively boost the bass.

Also I think 5 volts is to low for the 4558 opamp to function correctly.
