Klon buffer part substitution question

[Obie bong kanobie]

Ok so the out resistor on the klon buffer is 560ohm I only have 510ohms.  I wired it to be a always on effect so it's hard for me to tell if it's working ok like this or not.  Can this work temporally and what is it going to effect.  The output impedance?  I'm a newbie sorry
