I'm not a distortion user, but sometimes you need it for a specific job. I saw this tiny pedal and, after a couple of youtube videos, I decided to buy it.
I placed after my Full drive 2 mosfet and it really does the job for me. I can't be more happy with this little guy. Easy to use, almost no space on the pedal board and sounds incredible. What else can you ask for barely 50€?
As I said, I'm not using this pedal as a main sound, and never owned a distortion pedal before. So this is my personal opinion after 2 days of messing around with it. Maybe if you are in a metal band or something like that, you want to try something more specific.
