And they do what they are supposed to. The knobs feel sturdy, as does the chassis. Has ac jack and 9v battery to choose from.
Controls are easy to dial in.
This is a pedal for those who hate distortion pedals. I was unsure what this pedal would sound like into a high gain combo. It sounds great even with the dirty channel. It really distinguishes the different guitars I play. Definately an alternative to the tubescreamer or other highly praised overdrives.
