You completely ignored the solution I provided in post #2?

I have a simpler solution.

If you intend to use an LM386 as your speaker amplifier, why not just bridge Left Channel, Right Channel and Guitar into one mono amplifier? The sound output from an LM386 is so crappy you wouldn't gain any benefit from stereo in the first place.

 

Do we need to draw you one so you can built it ?

ok..give me a proper circuit diagram..that would be perfect.

i amr running a headphone as output right now...i can hear the stereo considerably god

i am trying to find a better amp ic..right now i am running a headpnone as output..and its working quiet nicely..i can hear the stereo signal considerably clear and the mono signal is present in both the L and R out of the headpnone

 

So it works great on your headphones. So why change it?
Because you want to drive loudspeakers.
LM386 is terrible for driving loudspeakers.

Why do you want stereo output from your loudspeakers?
You want to listen to music and play along on your guitar at the same time.
Do you really need stereo while you play your guitar?
Why not play your guitar through a separate instrument amp?

So many questions... so many answers.

A powered PC speaker makes a pretty good guitar practice amplifier, but it needs a JFET buffer ahead of the relatively low resistance volume pot.

 

Problem is he is confusing LM386 as buffers and mixers

i want my mp3 song in stereo..i dont want it in mono...because in my songs the effects that are used sounds horrible in mono..and i used lm386 for guitar signal amplification..i dont want to build a hifi amplifier..

i want to match my guitar tone with the tone present in the song..that is why i need stereo cause my song has different guitar tones in L and R out..

 

Problem is he is confusing LM386 as buffers and mixers

what ic should i use then?? can u give a complete circuit diagram ??

 

You do not care to look at the examples provided and you do not read the contents of the link I showed.
If you have read you would understand.

You cannot have the same tone as from the guitar played in the song matching what you play from your guitar.
For that you need to have proper guitar preamps and tone controls so you can tune the tone to your satisfaction.
If you do not read and do research on it, I cannot indulge in discussing how to make these things if you were to make mistakes in making the circuits.
Do your research. Enough examples and explanations is provided through this whole thread.
You keep repeating the question over and over again.

 

Post #2 is a concept schematic that shows the standard approach to a single mixer channel; build two for stereo. Post #26 figure 2, and post #27 are complete schematics that meet all of the requirements you have given us so far.

If the guitar input needs more gain than the MP3 inputs, that can be done by increasing the values of the input resistors for the guitar channel. If you need a better guitar preamp with equalization, input impedance adjustments, etc., that is a separate circuit design that does not affect the basic mixer schematic you already have.

The LM833 is an older, specialized part that might be difficult to find. There are many other audio-quality opamps to choose from.

i used lm386 cause i had some of them in my home..i read the links..and i couldnt understand properly..i followed post 27 and used 2 lm386 as buffers..maybe that was not a good ic for buffering...but it served my purpose
