Silicon Fuzzface question.

Hello built a silicon fuzzface from Jack Ormans site. Sounds really cool. I just found out about the caculator at analog alchemy and punched in the values and it said that I should be using a 220ohm resistor instead of 330ohm. What would this do to the circuit? It's fine as is, but I was just curious to know the effect it would have on the circuit and I guess...what purpose the reistor serves.
Thanks,

Some people like to increase that resistor up to 1k because the FF has no much volume with a 0.47k or less.
At the same time a 100k volume pot is used instead of the 500k.
