The title pretty much says it all.

I was just wondering, seeing as my amp is currently in process of repair and I have nothing else to play through.

Is it possible? Would I need a special lead? Etc.

yeah dont do it, just play it unplugged, if your playing at home, you can just play unplugged anyway, thats what I do when I wake up in the middle of the night with an idea for a song, I just cant remember the song after I go back to bed though...
