If your pedal has the BLUE switch, which a 2007 almost certainly does, than go by that pic on his page.
I've done it once, very ez, but I know how daunting it can look if you've never done electronics before!
best,

I put a switch on my Rat so I can go between the modded and standard sounds, but I never use it modded. |

Heck, you could even replace the broken resistor for hardly anything.

The problem is, you'll probably have to buy a small bag of them, since they're rarely sold individually (it's just not practical). It's only a few bucks - you just need to find a match and de-solder the one that's in there to replace it.
Care to show us a photo of the board where you made the cut?

Is that what you mean? |

| | | | no, i just plugged it in and couldn't get a decent sound. all i was getting is feedback, not the screeching loud feedback, but the kind of deep type of feedback |

| | Registered User | | Join Date: May 2009 Location: Minneapolis, MN | | | I am trying to do this mod, but also on the 560 ohm resistor, and I was wondering which resistor that is. On the DIY guitar amp site, it shows the gut shot of an actual rat, but only shows the 47ohm resistor, not the 560 one.
Thanks for the help TB! |

| | | | I just did this, and it actually does make a huge difference in the sound |

| | Registered User | | Join Date: May 2009 Location: Minneapolis, MN | | | I am hoping it does, all the 1k pots I find seem to have three prongs, but there are only two holes in the circuit board. The mightier mouse directions have a red line connecting the first and second prongs, does that mean I solder them together? Sorry for all the questions, I just don't wanna mess up my pedal. |
