Ok, I'm looking at a Big Muff.

This is probably an obvious, dumb question to most of you guys, but here goes...

There is a 560R from the sustain pot to common (see, I must be learning. I wouldn't have had a clue where it went last week!). If I don't have a 560R, but have a 510R, what would this do to the sustain? Would it make a huge difference, given that theoretically the upper boundary of a 5% 510R and the lower boundary of a 560R overlap by a few Rs?

I know, they have alternate upper and lower boundaries respectively and these are quite far apart, but I'm considering that something like this may have a significant tolerance outside of the boundaries of the noted value. I'm just trying to get a feel for tolerances.

I know a resistor would most likely be more significant in, say a power or gain stage or an IC/transistor connection (there I go again with that there learning stuff!) so I'm pretty sure a suck it and see attitude wouldn't do any damage and I'm thinking changing the resistor here would simply govern the amount of signal taken to ground from the sustain pot so I'd see more or less sustain?

So, am I talking nonsense in my reading of what might happen and why and what would the effect be?

Thanks. :)
