650k replacement for Parasite Wah

[Dali]

Hello,

Parasite Wah ask for a 650k resistor. Since Tayda only have 620k and 680k should I: buy the closest one? Is there some rule of the thumb to better go under or over in such case?

Or should I look at another store 'cause that value change everything...?

Thanks for any tip!

In some circuits, close enough is fine. For this one I would put two resistors in series to make 650k.
