@Noisembryo has some RAT pedals on his board as you can see in this thread.
Curious how he plays the original RAT. I actually got the Rattler on my board that @sfadams linked. That one won’t go off my board for a long time. The Aftershock was a really close call when deciding on a dirt pedal. With the Aftershock you also get a fuzz included similar like the Chase Bliss Brothers.

You can also combine two pedals to get the job done. For example when you combine a B3k with a rat tail/king pedal for a more dirty sound. I’ve seen on other forums lots of combination suggestions. I guess an EQ pedal before OD can achieve something similar?
At the moment I’m intrigued by blend pedals or actually 2 channel pedals with a clean channel and dirty.
