The BBE Green Screamer effect pedal is a vintage overdrive capable of producing a dynamic range of smooth and warm overdrive tones associated with vintage tube amps. The overdrive pedal features rugged construction that can take a beating, thanks to its heavy-duty die-cast chassis. Fat knurled knobs let you dial in your ultimate tone with your toes. The status LED light lets you see the pedal is engaged even on a dimly lit stage. A non-skid pad on the bottom reduces movement, so you don't have to chase your pedal across the floor. True hardwire bypass switching ensures it has no effect on your tone when its disengaged. The BBE overdrive pedal's easy access battery compartment is included so you don't expose your circuitry every time you need to change the battery.
