Controls include a bass boost switch, volume and gain knobs, and a tone knob that acts as more of a 'presence' control than the traditional tone control found in most overdrives. The Phat Axx is completely true bypass and includes a 9v "Boss style" power jack.
There are two versions of the pedal being offered - one of them is in a diamond plate enclosure, while the cheaper version is in a hammond box. The same circuit is inside however. The diamond plate enclosure is a bit more expensive since the case alone takes several hours to fabricate from start to finish.
Bass boost/cut switch
Completely True Bypass
Optional Custom made Diamond Plate/Poplar enclosure with copper shielding for extra noise protection
