And while they were at it, they designed it to work for the more modern drop tuned heavy stuff too. Made sense since those tones were due in large part to guitars being played through amps designed for bass. They also designed a pedal that FINALLY let you control the amount of grind solely based on your finger attack. You know the feeling - full and rich and clean when you brush lightly and some nice wooly edge when you dig in. At the other end of the sonic spectrum we wanted a drive pedal that could deliver bone-crunching grind and still hold together without sounding thin or turning into a sludgy mess no matter how hard you hit it.
