Up for grabs is an absolute investment-grade collector's piece: a virtually mint condition, DOD 50th Anniversary Overdrive Preamp 250, complete with its original commemorative box and all the factory case candy.

This unit is stamped with a highly coveted, low three-digit serial number: #520.

To celebrate 50 years of an icon, DOD hand-built a strictly limited run of only 1,974 units worldwide right in the USA. This isn't just a standard reissue; it is an absolute tribute to the legendary 1974 gray-box circuit, built to the highest possible standards.

The 50th Anniversary edition features an exclusive 3-way toggle switch on the side, allowing you to access three distinct clipping eras of the 250 circuit:

Silicon Mode: The classic, aggressive, hard-clipping drive that pushes high-gain amps into tight, biting classic rock bliss.

Germanium Mode: A warmer, saggy, highly compressed boutique clip that makes single-coil pickups sound incredibly fat and singing.

Lift Mode: Removes the clipping diodes entirely, turning the pedal into a massive, high-headroom clean preamp boost to slam the front end of a tube amplifier.

Condition: Mint / As-New. It has only been unboxed for verification and testing. Never gigged, never velcroed, and entirely free of blemishes.

Box & Candy: 100% complete. Includes the original anniversary outer box, custom control topper, plectrums, stickers, manual, and all original case inserts.

Serial Number: Fully documented, low three-digit serial number (#520 of 1974) cleanly printed on the factory chassis label and box.

Functionality: Flawless. Pots sweep cleanly, switches engage with zero noise, and the circuit operates perfectly.

With only 1,974 of these existing globally, clean low-serial examples like this are disappearing into private vaults rapidly. Perfect for a high-end collector, a studio tracking board looking for the ultimate 250 variant, or anyone who wants the ultimate stomp box experience.
