I like adding a green ringer to a fuzz. And that’s what I use on my board. But as far as Octave Fuzz goes, I like the Super Fuzz. I have a BYOC that gets played a few times a year. The chugging sound I get with it is fun at home, but not a sound I use when I gig. Not yet anyway.
I suggest modding the “tone” switch on the super fuzz. Instead of a switch for scooped or non-scooped, put a Pot in there and you have more scoop ability.
And while you’re filling your cart, the Propolis is a blast. No knobs. Just gated octave fuzziness.
And one last thing. Build all of them. You’ll be happy with the results.
