I would say its like a super trebbly tinny distortion. Now I was using the blend and presence at full when I noticed it. But I turned the drive, the blend, AND the presence all down and turned the level up so I could hear it, and same thing.
I did buy the pedal brand new from Guitar Center back in February, wouldnt be able to find the receipt though.
If you guys require further testing on my end, I wont be able to try anything until I return home this Friday.
On a side note, I did take the pedal with me a few weeks ago, and it wouldnt work with a battery, only when powered by AC.
