This pedal is a modified version of our Box of Rock’s Distortron Engine. The improvements include a gain boost switch for added sizzle and a sub control switch with 3 levels. The amounts were carefully selected to reduce “flubbiness” that occurs when using amps with heavy low-end response. It would be immodest of me to suggest that this ZVEX effect is the greatest distortion pedal of all time, but it probably is. Try it last in your chain, and beat it up with your other effects... it stacks like a dream. .

Pedal Dimensions (LxWxH): 4.70" x 2.38" x 1.82".

The Distortron™ is the gifted little sister to 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 may use the Distortron™ effectively with many different amplifiers, but to get the sound I heard when I de- signed it, try it through an old-school non-master volume Mar- shall at least once. You may 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.
