MXR Sub Machine Octave Fuzz

I love this pedal, it just sounds like a Fuzz should sound for my taste.
In my favorite setting, it sounds fat, plenty, aggressive, cutting and heavy. But is very versatile too, I use it in my pedalboard for gigging. It can sound like a super fuzzy classic pedal (fuzz face) and it can be a totally different prog sounding pedal thanks to its low and high octave matched component.
I think it's a very versatile fuzz because in addiction of having a high and low octave (that you can mix choosing to be clean or distorted as well) you have a tone knob which really affect the nature of the sound as you desire, you have a volume knob which really help to obtain the sound you want matching it with the last knob: the fuzz amount, that really goes to 11.
Overall, I'd say it's a very solid constructed pedal, sounding great, versatile enough and very funny to use especially if you love to experiment with sounds!
