2 Channel Mixer Circuit

[ZACKF]

The regulator ground reference MUST be taken from the OUTPUT node where power is sent to the next circuit..

All the grounds are connected, and there is also a jumper for ground to the next circuit. I didn't show it on the layout! woops! sorry. 😀

I agree, but in this partticular design, effects stage is implemented as
if it were a pedal with a wet dry knob, i realized later that i should have
considered putting it at the power stage, but i left it as is, theres no
reason why it shouldnt work.

Hi,

And there is no reason why you need a mixer at all, your effects
has one, wet is effects, dry is the guitar, your overcomplicating.

Set up as pedal, a multi-effect also completely replaces the
amplifiers input channel, which should be set to clean and
simply left there, input distortion is not good post effects.

That's a good point. Even in this circuit, I can probably scrap the pan/mixer pot and just adjust the gain of the effects by adjusting the input resistance of the op amp right?

Hi,

Simple fact is the whole point of this thread is all wrong.
No understanding and belligerence to getting the point.

I'm not going to try to help anymore, ignorance is bliss.

I understand your point, no mixer and put the output of the microcontroller before the power section. I thank you for your input.
