So I have a 1/4 to 1/8 adapter, I plug this into my mic, make sure control panel and soundcard specific settings are maxed and with the mic boost. I go into ableton live 7 and create an audio track set my in to external and load Guitar Rig 2. Whenever I play I hear the sound of the Preset PLUS the sound of the guitar without the preset... I've never had this problem before. I tried recording on my laptop without a problem but my laptop recently suffered from a fatal accident where one's cat knocks it off the table and it smashes >_>
That is because when you plug things into the Mic input the computer is set to monitor it. Try plugging into your Line input instead.
