Nicolas said: hum wait wait, im a little confused there, i thought both the big muff and the little big muff were made in NYC .. ..
so what, how many models of the big muff is there around ??
A LBM ?
B LBM ?
NYC bif muff ?
NYC Muff Pi ?
and the russian one ?
I think Jelly meant it as "a LBM", not "A LBM", it's not a different model or something.
EH made Big Muff variations in the 70s, then released the Big Muff Pi which was the most successful. Sovtek made a lot of variations on the Pi in the 80s/90s. Then EH reissued the original vintage Big Muff Pi as the "New York Big Muff Pi", to differentiate between it and the Sovtek reissues.
There's a vintage EH pedal called the Little Big Muff PI:

..the new one is just "Little Big Muff" and sounds somewhere between the NYC Big Muff Pi and the green Sovtek version (the best in many's eyes). .
