The ZVEX Distortron is the gifted little sister to the ZVEX 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 try it through an old-school non-master volume Marshall 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.
Sets the amount of distortion. Start around 1:00 o’clock. Drive is based on my original Super Hard-On gain control, so it may crackle when turned. This is perfectly normal.
Adjust for treble content. Start around 2:00 o’clock.
Adjust for output volume level. Start around 9:00 o’clock.
“Lo/Hi” lets you choose standard “Box of Rock” gain level or a slightly boosted level.
“2-1-3” lets you choose the full “Box of Rock” sub amount (3) or two different lower levels of subs depending on your amp’s needs.
