The best quality EQ pedal I've ever had, I'm glad I bought it, although it's not cheap at all... I use it for an electro-acoustic guitar, it gives a little warmth to the sound while taking the scratch out of it. I used a Boss GE-7 before, I was a little afraid that the 6.4k frequency would be missing, but I don't feel the lack at all, and it's almost noiseless. Its exterior appearance is nice and sophisticated, and the blue LEDs are beautiful :) The disadvantage may be that it doesn't have a Level pot, but if you don't want to boost with it, then this won't cause a problem either. The footswitch is a bit loud, and a power supply is highly recommended, because a few hours of intensive use drains the 9V battery, and changing the battery is quite cumbersome, because you have to remove the 4-screw bottom cover. Anyway, a totally phenomenal pedal!
