EDIT 7/OCT/ 2020: I just got the pedal back from Thomann and to my surprise MXR did indeed repair it without added cost, so I have to take my words back and say that I am indeed very satisfied!
ORIGINAL REVIEW:
I would advice everybody against buying this product. At the beginning, as long as it worked as it should, the pedal was actually great. I bought it exactly 2 years ago, but for the last year I haven't used it at all as I have other EQs/Preamps. To my surprise, when I wanted to use it again I discovered that one of the bands (the 8k) was producing crackles and noise depending on its position. Also 4 of the LEDs were not working properly. As I still had Guarantee (one year left), I sent the pedal back to Thomann and they sent it back to MXR. The response from MXR: the problem is caused by wear and therefore no covered by the Guarantee. They want 100€ in order to repair it! (60% of the price!). Obviously the quality of the components used by MXR there is not high enough in order to hold not even a year of light use (in studio, I didn't even tour with it!).
After doing some research, I discovered a lot of forums posts where multiple users were reporting identical or very similar problems with this very same pedal.
I'm very disappointed with the service offered by MXR.
