Really love this pedal so far, it's my first fuzz pedal and it's the exact sound I want, just a crazy vintage fuzz tone. The build quality is way more than what I was expecting, compared to £30 joyo pedals. They feel really solid and the knobs don't feel cheap at all.
The only "issue", is that the switch is quite soft, (not a very clicky one), and engages when you release the switch, as opposed to engaging as it's pressed. This doesn't bother me, but it's definitely unconventional.
