Position the guitarist and vocalist. For a long recording session, a seated position is best for the guitarist. If you're recording yourself, select a position that allows access to your recording hardware and software.
Record the guitar with a single microphone on a stand in front of the guitarist roughly five to six inches away from the guitar's 12th fret. To record the guitar with two microphones, place one stand in front of the guitar's bridge and another in front of the 12th fret. Adjust the stands until both microphones are the same height and five to seven inches from the guitar.
Adjust a stand until a microphone is level with and five to seven inches away from the vocalist's mouth. Attach a pop shield to the stand to protect the microphone from the singer's saliva and reduce popping sounds when vocalists sing certain consonants, such as the letter "P."
Connect the microphones to the audio interface. Provide each microphone with phantom power by pressing the phantom-power button on your audio interface or using an external power source, as applicable. Phantom power is the power source required to operate condenser microphones that is transmitted through XLR cables.
Launch your recording software and bring up the volume monitor. Play single notes and chords on the guitar at varying levels. Monitor the volume to ensure against clipping, which occurs when the incoming audio is too loud, causing distortion. If clipping occurs, lower the microphone input volume on the audio interface or move the microphone farther from the guitar.
Sing into the microphone at varying volume while monitoring the levels in your recording software. If clipping occurs, lower the input volume level on the audio interface or move the microphone farther from the vocalist. Move the microphone one inch at a time to find the best position.
Create one recording track per microphone in your recording software. Press record.
