not a clone, but oktoberfest isn't hard to make:
1/3 each of pils/munich/vienna to a mid 50s gravity, mash at 152, 90min boil, 25 ibus of noble hop at 60, your favorite german lager yeast (WL830) pitch at 48df, ferment at 50df, lager at least 4 weeks after primary. tap, serve. voila.
moderate carbonate water helps (I use ~100 -150 HCO3)
I make mine with a lot more vienna and a little bit of late hop (2oz in 12gal at 20min) but that's just me.
that'll get you really close, and you may like this even more.
