Pretty much a brand new pedal I’ve only used a few times. Perfect for overdrive and distortion.

Sweetwater says:
On the cusp of DOD's release of the limited-edition 250 50th Anniversary Edition pedal comes the 250-X, an overdrive/preamp based on the original OD250. Like the 50th Anniversary Edition,DOD equipped the 250-X with the same trio of voicing options. From the stock silicon-fueled sound of the original to Asymmetrical mode to a handy Lift mode that functions as a high-octane boost, this pedal’s triumvirate of tones makes it the most flexible and expressive OD/Pre 250 that DOD has crafted to date. And true to the 50th Anniversary, the Overdrive Preamp 250-X brandishes a brilliantly redesigned enclosure that harkens back to the original with a metal flake gray finish and vibrant yellow silk-screening. Destined to become a classic among discerning tone seekers and stompbox collectors alike, the Overdrive Preamp 250-X is the ultimate iteration of the DOD dirtbox that started it all.

When the DOD 250 first launched in 1977, it sported a simple and efficient arrangement of a single Gain knob and a single Level control. And while this no-nonsense combo is just as relevant today as it was in the late 1970s, DOD’s Overdrive Preamp 250-X refreshes the original recipe with enhanced sonic possibilities. Thus, this pedal’s 3-position switch unlocks a trio of distinct clipping options to choose from.

Silicon: This setting captures the OD 250 as it first appeared in 1977, providing a raw, gritty response with plenty of gain on tap.

ASYM: Flipping the switch down produces a rich and dynamic asymmetrical even-harmonic distortion that forms a perfect sonic complement to the OD 250’s traditional sound.

Lift: Finally, this setting eliminates diode clipping from the circuit entirely. And while the Lift voice makes for a perfect clean boost, Sweetwater’s dirtbox die-hards particularly love the sweet saturation that begins to flood your signal when the LM741 op-amp is pushed to its limits on higher settings.
