Throw away your Tube Screamer. Truck loads of sweet creamy overdrive have arrived. The more you turn it up the better it sounds. The Interstellar Overdriver is a real overdrive pedal blasting your amp with your sound. The knob works giving a slight boost all the way counterclockwise to a beautiful harmonically rich overdrive maxed out. It is designed to work the same way as old tube amps - the more you turn it up, the better it sounds. For more control kick back the output volume with the MASTER knob while keeping the sweetness.
