The Z.Vex Distortron is very like the Z.Vex "Box of Rock". It is highly specialized to simulate the "everything on 10" sound of a classic Marshall JTM45 non-master-volume amplifier. You can also use the Distortron efficiently with many different amplifiers. You can use your guitar's volume control to adjust for the exact amount of distortion you need, all the way down to very clean and clear with most drive settings when the gain switch is set to "Lo."

Plug your guitar (or any effect's output) into the right hand input jack. Plug the output into an amp or other effect's input. Rock out. Set the subs switch so there's just enough low-end for your amp. Try turning up the gain all the way but leave the gain switch on Lo. This is the maximum gain where you can still turn down your guitar and get a completely clean tone if you need it. With the Gain switch on Hi you can get more singing sustain with feedback at moderate amp volume. Try using your rhythm pickup with the tone control turned all the way down for a vintage bluesy howling lead sound.
It's recommended that the Distortron be the last last in your pedal chain, just before the amp. Set the amp for your favorite clean tone, set the Distortron for your favorite distortion tone. Should you be using it conjunction with a booster pedal then try it both before and after the Distortron
Before - the Distortron will give you more sustain
After - the Distortron will give you more amp volume
