Line Out in Place of a Microphone
If you're new to recording and don't own a microphone to place in front of your amplifier, you can use the Line Out on your amp. This sends a line-level signal (not powered, like the speaker out... don't use that) via cable to your computer. if your computer has a 1/4" microphone input, you can use a cable that runs from 1/4" (out of amp) to 1/8" (into computer). Though the tone of what you're sending doesn't include the sound you like from the power section of your amp, your speaker, or cabinet... it's better than nothing. Yesterday's tip was to use two amps for recording. Since you're looking for a different sound from your second amp anyways, using your line-out will sure do that.
Have a great weekend everyone!
