The idea of a 2 in 1 pedal with a Graphic EQ and Tuner really appealed to me as a space saver on the pedal board. I have an old Boss EQ pedal which is excellent, but the addition of the built in tuner sounded like a good option to save space. This pedal looks great and is well built, but the EQ is quite poor I'm afraid. I thought this would be just like my Boss EQ with a tuner built in, but it's not. The EQ on this pedal is very limited in that the range is not very linear. As you move the sliders up and down there is no discernible difference in the EQ until the sliders reach their max position, and even then the tone still isn't right for each frequency band. However, this is a very affordable pedal with some good features so all is not lost. I now use this pedal as a "Boost" in my effects loop when I need a bit more oomph for lead playing. I use it to boost the mids and my volume, and I can also check my tuning too!
