so, I'm investing into a fuzz pedal, and have chosen three I really like:

-Truly Beautiful Disaster
-Red Witch Fuzz God
-Zvex Fuzz Factory

my question is, which would be the best investment? I would like tone of these since they are oscillating fuzz, and i love oscillation. I mainly would use it for art rock, psychedelia, and experimentation stuff. If you have any suggestions, please help me!

thanks in advance
