Welcome to io, where your super-distortion hunt finally ends. Packed with high-gain transistors and meticulously hand-picked components, the io is one of the fattest, heaviest, most gut-churning, Marshall-on-steroids dirt boxes around.
Three simple controls let you unleash the grit: Volume, Tone, and Gain. The Volume control does just what you'd expect. The Tone control works as a roll off, so turning it counter-clockwise will roll off high frequencies and keep the low frequencies intact ("adding" bass), and turning it clockwise will roll of low frequencies and maintain highs ("adding" treble). This type of control keeps the original input signal intact, just as your guitar sent it, so the circuit adds no coloration. The Gain control lets you set just how distorted you want your sound to be.
The io Super-Distortion comes in two flavors: Etched and Hand-Painted. The etched finish is hand sanded and polished, and sports metallic red paint in the recesses. The painted version begins with a coat of metallic red paint — then, each pedal is hand distressed, burned, and charred to taste so that no two are alike. When you get yours, be sure to take a nice, long, up-close look at all the detail.
As with all my effects, only the finest quality parts are used: cast aluminum shells, Switchcraft jacks, individually selected transistors, carbon resistors, high-end capacitors, and personally designed plate-through PCBs. The io is true bypass, sports heavy-gauge wiring, a 9-volt center pin negative (BOSS style) DC jack, and an internal battery clip. Made by hand, one at a time, here in the USA.
