A Historic Reimagining of DOD’s Classic Dirtbox

DOD marks 50 years of sonic innovation with a bold tribute to one of its earliest and most iconic pedals — the Overdrive Preamp 250. The 50th Anniversary Edition isn’t just a vintage reissue; it’s a fully reimagined evolution of the 1977 classic, now handbuilt in the USA with premium components, expanded tonal flexibility, and a commemorative design that honors DOD’s legacy.

Three Voices, Unlimited Character

At its core, this special edition keeps the spirit of the original 250 alive — raw, gritty, amp-like overdrive with the vintage LM741 op-amp delivering that unmistakable edge. But this time, DOD adds a 3-position clipping switch that transforms this one-box wonder into a tone chameleon:

• Silicon Mode: The original voice — pure, aggressive, and saturated.

• Ge/ASYM Mode: Asymmetrical clipping via a germanium diode for smoother, more harmonically rich breakup.

• Lift Mode: Removes the clipping diodes entirely, delivering an expressive, open-voiced boost that gets crunchy when pushed.

Built Like the Originals — But Better

This limited-edition 250 is built with premium through-hole components, mirroring the values and feel of the original, while updating the enclosure with a lighter aluminum chassis. It sports a metal flake gray finish, vibrant yellow silk-screening, a yellow/green LED, and a laser-etched aluminum 50th Anniversary badge. It’s rugged, refined, and ready to become the crown jewel of any pedalboard or collection.

Why This Pedal Stands Out

This isn’t just a nostalgia piece — it’s a high-performance drive/preamp pedal with studio-grade detail and road-ready build quality. Whether you’re chasing gritty 1970s overdrive, rich harmonic crunch, or a powerful clean boost, the DOD Overdrive Preamp 250 50th Anniversary delivers with vintage soul and modern flexibility.
