With MOSFET clipping under the hood, this pedals overdrive is a smooth purr that can be pulled back for a nice, clean boost or cranked into full gear for vintage high-gain grind. A simple set of controls allows you to dial in the right sound for your setup, featuring your classic output, tone, and gain controls along with a Boost/Cut switch that allows you to bump up the overall level with a little extra midrange or drop everything down a notch. This pedal sounds killer on its own, but we think it sounds simply sublime when used to rev up a tube amp thats just about to cross the line. True hardwire bypass. Powered by 9 volt battery or AC adaptor (ECB003) not supplied.
