DOD GFX70 Extreme Distortion pedal

The DOD GFX70 Extreme Distortion is one of the heavier voices in the later DOD / DigiTech family. It takes the thick, saturated spirit of the earlier Metal X style distortions and reworks it into the GFX series format with simple, effective tone controls and plenty of gain on tap.

Unlike some classic DOD boxes that sit closer to hard rock, the GFX70 leans straight into high gain territory. It delivers a fat, harmonically rich distortion that can cover chunky palm mutes, thick sustained chords, and noisy experimental textures when you really open it up.

The GFX70 layout is straightforward:
  • Level: Overall output volume.

  • Low: Boosts or cuts bass for tight chugs or big, boomy grind.

  • High: Adds bite and presence so the sound slices through a mix.

  • Gain: Ranges from strong crunch to fully saturated extreme distortion.
With Gain set past noon, the pedal moves into its “extreme” identity. Many players keep the Low just below center and the High slightly above to balance tight low end with cutting attack.

The GFX70 shows up on boards for metal, hard rock, punk, industrial, and noise players who want a more modern, aggressive DOD flavor. Common ways to use it include:
  • Main rhythm distortion for heavy riffing and palm mutes.

  • Stacked after an overdrive or boost for saturated lead work.

  • Last in the chain in experimental or noise rigs to overload delays, loops, and odd signal sources.

  • Paired with bright speakers or modern mics for a sharp, cutting recorded tone.
Rolling back the guitar's volume control can clean the GFX70 up just enough for verses or quieter parts, then a quick turn back to full returns the full wall of distortion.



Divider icon Place in the DOD lineup Divider icon

In the broader DOD story, the GFX70 Extreme Distortion belongs to the later era where DOD and DigiTech were updating the look and expanding high gain options. It feels like a spiritual descendent of pedals such as the FX70 Metal X, but with the GFX series cosmetics and a slightly different voicing.

Compared to earlier FX series distortions:
  • FX55 Distortion - more classic rock and early metal; the GFX70 has more gain and a more modern, aggressive edge.

  • FX56 American Metal - voiced for older metal tones; the GFX70 pushes further into saturated, bright, cutting territory.


Divider icon Suggested starting settings Divider icon

These are only suggestions, but they can help you find the GFX70 'sweet spots' quickly:
  • Modern rhythm - Level to taste, Low just below 12 o'clock, High around 1 o'clock, Gain at 2 o'clock.

  • Thick lead - Level slightly above unity, Low at 1 o'clock, High just under noon, Gain between 2 and 3 o'clock.

  • Noise / experimental - Level at unity or higher, Low and High near max, Gain maxed, and use volume pedals, loops, or oscillating delays in front.


Divider icon Collector notes Divider icon

The GFX70 is not as common as some of the earlier FX series pedals, but it still surfaces regularly on the used market. Prices vary based on condition and originality, with complete, working examples generally being the most desirable.

Things for collectors and players to watch for:
  • Missing or damaged battery doors.

  • Crackly jacks or intermittent footswitches from heavy use.

  • Cosmetic wear on the graphics from years of gigging or practice.
A clean GFX70 makes a nice companion to other high gain DOD and DigiTech boxes and fills the "extreme" slot nicely on a DOD-focused board.



Divider icon Known quirks and tips Divider icon
  • At very high Gain and High settings, the pedal can become noisy. A noise gate or backing the High off a bit can keep things under control.

  • Running it into a slightly driven amp can smooth out the top end compared to a very clean solid state amp.

  • If it feels too sharp, try lowering the High and boosting upper mids on your amp instead of cranking treble on the pedal.
The DOD GFX70 Extreme Distortion is not a subtle tool. It rewards players who want bold, unapologetic distortion and are willing to shape it with picking dynamics, guitar volume, and amp EQ to taste.
