DOD Overdrive Preamp 250-X

The Overdrive Preamp 250-X is the 10th evolution of DOD’s legendary OD250, designed to deliver unmatched tonal versatility for players of all levels and styles. With three distinct distortion modes and modern refinements, it’s the most flexible 250 yet.

At its heart, the 250-X keeps the same Gain and Level controls that made the original a classic, while expanding the sonic palette with a three-position toggle switch:

• SILICON – symmetrical clipping for the iconic 250 sound

• ASYM – asymmetrical clipping for rich, even-harmonic distortion

• LIFT – removes diode clipping for a clean boost at moderate settings or a dirty boost at higher levels, pushing the vintage-style LM741 op amp

Housed in a durable aluminum chassis and weighing just 8 ounces (250 grams), the 250-X is built for both stage and studio. Features include:

• True hard-wire bypass

• Modern 9V DC power input (+18V tolerant circuitry)

• ¼” input/output connections

Whether you’re after classic grit, harmonically rich drive, or a powerful boost, the 250-X delivers it all in a compact, road-ready pedal.
