Krankasaurus Gain Issue?

[Roctopus]

I just finished putting together a Krankasaurus, with a board I etched myself, and noticed that the gain/drive section sounded really woolly/fuzzy. The boost section sounded fine. I checked first to see if there were any solder bridges but everything looked ok. After double checking the parts I did noticed that the value for R5 was 430k instead of 470k. The place where I buys parts must have accidentally sent me a 430k resistor instead of a 470k. I never bothered to check the color code and just assumed they sent me the right stuff. Anyway, I wanted to know if this is the reason why it's not sounding right. I can't think of anything else that might be causing it. Thanks for the help gang
