    About the GREENHOUSE EFFECTS Sludgehammer

    The Greenhouse Effects Sludgehammer is a distortion/fuzz pedal tuned for Doom, Stoner and Sludge metal.

    Put it in front of your amp's clean channel (set with a little bit of hair) and cause havoc with your dowtuned riffage! 

    From crunchy rhythm to all-out fuzzy annihilation, the Sludgehammer is surprisingly versatile too. 

    Sludgehammer Controls

    Volume Adjusts the output volume of the pedal

    Vintage Thicker, darker, looser

    Modern Brighter, tighter

    Gain Adjusts the amount of gain, from rhythm crunch to a thick wall of fuzzy distortion.

    Tone A wide ranging control which allows you to dial in enough bite to cut through a dense mix - or dial out the treble if you prefer a smoother, darker sound.

    Body Adjusts the response of the low-mid frequency range, and is interactive with the Tone control.
