Thank you so far :)
I´ve solved the problem, but as you now the solution of one problem, leads to another
My new problem:
Now I get my DI signal perfectly through the amp (I´m using the Headphones output), but if i want to capture the signal from the Microphone into my DAW there is a big feedback, because it´s a circle (Headphones out > Amp > microphone > Pod > Headphones out with DI and captured signal from the amp > Amp > microphone = Feedback)
I´m using Logic, and in the Audio settings there is the option of "Software Monitoring" and "independent Monitoring Level"
and no matter how far I put the faders down, I can still hear a signal through my Headphones (and with that, through the amp later).
So it seems to be a problem in the combination of teh Logic and POD settings of my monitoring
The solution:
The solution is to record my microphone signal, without any monitoring.
The question is:
How do I do that?
