The heavy metal pedal of your dreams has arrived. Most pedals on the market that are designed for Hard Rock and Heavy Metal sound nasally and thin. They have the bite, but without the beef. However, the Mark V fattens your tone. Keep the dial turned down and you get a rich, warm Hard Rock sound. Crank the dial up and you get a sound parallel to a Mesa Boogie Triple Rectifier, aka Metallica And Justice For All.
