Maybe the tremelo thing is only a theoretical possibility-

And seriously, I am the orginal band-in-a-box lead player. I am particularly fond of settling up demented convergences, such as Polka versions of Paul Simon songs, or my infamous "Danny Boy Mambo", and then looping endlessly into the night. When I started this, I lived in a ground floor apt, and thought no one could here me--I later discovered that I was being heavily disrespected by a classical guitarist who lived on the fourth floor. Turns out you could hear me loud and clear in the laundry room.
