The Russian Plague is a doom players dream come true.
A Rat circuit stacked into a Cival war Muff. You can also change the effects order with flick of a switch
Gargantuan tone. Absolutely indispensable to my playing. Fantastic build quality. Love it.
And absolute sludge is bloody right, this thing paired my with my Orange amps is pure doom heaven!
The muff side gets you the classic doom tones likening to mastodon, sleep, bongzilla and when dialed back has a nice classic fuzz that's great for rocking out to some grunge other fuzz rock or punk tones.
The modded Rat side is incredible on it's own, I have to admit I was a bit skeptical of it since I went out of my way to get an old eat years ago and couldn't gel with it but this side is amazing for that sweeped or mid scooped kinda tone, this side I also found to be able to manipulate more with my amps EQ.
Now for the main course - both sides on together is pure f*cking sludge - paired with an orange amp or a Randall that I've used, I'd honestly say its Crowbar in a box, or Corrosion of Conformity, Down or even King Parrot.
I highly recommend this pedal to all the doom guys out there!
