Rangemaster question

[halfmassive]

Hello,
I'm new here but have been reading and planning out projects for quite a while.  Thanks for all the info and awesome projects!

I have a question about a rangmaster that I just built.  I built it on vero board and everythign works great and the pedal sounds excellent, except when I roll my guitar volume down I get a crackling sound while the pot travels.  Is this normal for a range master or is there something I should do to correct it?  The circuit I made is stock except for a switch for 2 input caps and a 1 meg pulldown resistor.

Thanks very much!

I fixed it.  Turns out I had my pulldown resistor wired incorrectly.
