DigiTech DOD Overdrive/Distortion Preamp 250 Guitar Pedal, 50th Anniversary

The Overdrive Preamp 250 – 50th Anniversary Edition celebrates the iconic legacy of one of the most influential overdrive pedals in music history. Originally introduced in 1974, the Overdrive Preamp 250 helped define the sound of rock and metal during the late ‘70s and early ‘80s. As a limited-edition release, only 1,974 units will be made, making this pedal a rare collector's item. Hand-built in the USA with meticulous attention to detail, this pedal features the same authentic design as the original but with modern enhancements for added versatility. With its three distinct overdrive modes, this pedal is a perfect fusion of vintage sound and modern customization options for players and collectors alike.

The Overdrive Preamp 250 – 50th Anniversary Edition pedal offers a unique experience with three different overdrive circuits in one. Switch between the original Silicon mode, which replicates the famous bite and grind of the classic pedal, or select the Ge/ASYM Germanium mode for a smooth asymmetrical clipping with exceptional touch sensitivity. For a more transparent boost, engage the Lift mode, which bypasses the diodes for clean boosting or op-amp rail clipping at higher levels. This mod-friendly pedal also features a socketed LM741 op-amp and through-hole components, making it easy to modify just like the original 250 pedal.

The anniversary edition is not just about sound; it’s about celebrating the rich history of the Overdrive Preamp 250. With custom artwork, a color-matched LED, and a 50th Anniversary pedal topper, this pedal is an absolute must-have for players who appreciate quality and collectors who want a piece of musical history. Whether you’re performing on stage or adding to your collection, the Overdrive Preamp 250 – 50th Anniversary Edition is sure to impress with its timeless design and cutting-edge features.
