Hey, man! Great work, but I wonder why did you keep the guitar. I would like very much to busk with this, but I would need the guitar to be removed from the track. Karaoke-version dot com dont have it. Can you contact me? I want very much to buy your guitar removal, and/or a minute of your time teaching me how to do. Please e-mail me at guilhermebgirardi at gmail dot com.
