This nice and cheap EQ-pedal is a decent purchase if it's going to be your first one and if you are not super excited about EQ-pedals but just want to buy one to try. This certainly does its job and sounds fine too, and the build quality is not bad either.
I don't own any expensive guitar pedals so I'm not an expert, but this one seems like a decent pedal. The tuner feature is nice to have but a clip-on-tuner is much easier to use and more accurate.
The only thing that I really do not like is the switch which is quite stiff and makes an irritating click.
If you want to try out an EQ-pedal and 35 euros is not too much, go ahead and try this one.
