PROVIDENCE SDT-3 STAMPEDE DT distortionUsing the same power converter circuit as the Stampede OD, the output of a single 9 volt battery is increased to 15 Volts and delivers bigger sonic depth and wider dynamic range. The result is hard hitting distortion with a big low end that is similar to what you'd expect from a large amp stack driven hard. Gain and tone controls make it possible to dial in anything from a natural crunch to fuzzy, dirty distortion.
