This kid is right. The big muff is my favorite pedal, but I can never get a light fuzz (broken headphones/ satisfaction) tone out of it. It's pretty much a wall of guitar or nothing. If I were you, I'd think about Voodoo Labs super fuzz. That’s a fun one too. I wouldn't try a fuzz face either, I’ve owned one and I could get the exact Fuzz Face tone out of my Big Muff with a little EQ-ing. The fuzz face just isn't very versatile. If you do like the Big Muff, DO NOT get the Russian one, unless you just want to hum and pick up radio signals. Just spend the $30 more or whatever it is for the US made one.
I love fuzz pedals.
