In the words of Baltimore Sonic Research Institute:

Ashmaker is a distortion designed from the ground up for players looking for a two-channel drive with maximum flexibility for the stage or studio. Fine tune your sound with a three-band EQ and a wide range of preamp gain and then rip into the heavy riffs with the footswitchable gain boost. Ashmaker excels in low tunings and asks only for more cabs to deliver doom all the way to the back of the venue.
