dude, the russian one is kinda more like a distortion pedal rather than fuzz. go for the USA you wont regret it.
it seems to me like big muffs were made for offsets and fender amps, usa muff through the twin reverb will sound really creamy and nice.
the little muff is bassier and it has more sustain than the other 2 models and its great for the price. but i think the other 2 are better.
i dont really think the russian one has much quality problems, the knobs just tend to bend, but i think its more solid than the usa and the little big muff.
its your choice, basically they're similar, try them all out and see but i'd say save up the extra 10-20 bucks for the usa.
i think i'm going to buy another muff, a russian one i think. i bet that when 2 muffs are turned on, the sound is even more orgasmic.
