Like the title says. The russian pickle is the best fuzz. I used to have a bass muff. I've also had modded tube screamers, mxr blowtorch, and this a huge improvement and I can get all the fuzz tones in my head. I cant get a bad sound of it. Blows the others out of the water. With my spector, other worldly. Highly recommended. Added info: With a bassballs and octave. you get into synth territory.
