    Comments about Ernie Ball Expression Overdrive Pedal:

    I thought this would be so cool, I have always wanted a "variable type pedal". I plugged it in and the thing made my amp sound like it had a blanket over it. It completely changed my tone and removed all of the sparkle that my amp has, even in the all the way off position. It was not usable. It's just too bad because i wanted to love this thing, I was even willing to re-EQ my rig to accommodate the pedal but no matter where I put the knobs it was a mushy, muddy mess. It is built really well, though, and looked like it would last a long time. It just wasn't right for me.

    The fact that he pedals tone always affects your signal is rough riders anthem. Pedal's on the nos but kinda pricey
