How To Seperate Guitar From Song

• Get audacity
• Import .mp3 into Audacity (The song must be stereo)
• Split the stereo track
• Highlight the 2nd track.
• Go to "Effects" and click "Invert"
• Duplicate/copy the 2nd track and paste it (You should have 3 now)
• Set all the tracks to "mono"
• Track 1 will now be your guitar
• Tracks 2 and 3 will be the rhythm

The song should still be the same (Except of course in mono)
There are no differences in sound, but the guitar will be slightly audible during the song (especially during solos)

To test and see what the song will sound like, just hit "Mute" on the first track.
