Since a lot of people put a graphic EQ in front of their drive pedals, me included, either to shape tone or as a boost, putting both functionalities in one box is a relevant idea. At 59 Euros you don't expect the best overdrive on the planet, but this is definitely usable.
The graphic EQ range is +/- 18 dB but fader travel is only 2,1 cm. This means an enormous boost on the last 2 mm of the fader. Longer faders and +/- 12 dB would probably have done the job nicely. Apart from that, much functionality if you are on a tight budget.
