The Pusher is a compact one knob clean boost intended to "push" your amp a little while maintaining the same tone and dynamics. Many Blues/Country players told me they wanted a pedal that gave them their same sound with "just a little bit more". This is that pedal. Do not think it is a weakling though! When cranked up, the Pusher works great to push a tube amp into natural overdrive that you can still control with your guitars volume knob. The single knob is a gain control that boosts the lows slightly at higher settings.
