DOD originally stood for David Oreste Di Francesco, who founded the company in 1973 with business partner and musician John Johnson. David was the original engineer who, with his business partner John, later[when?] sold the company to Harman International. The engineer now runs a company called Rolls Corporation.
Over DOD's 40-year history, the company introduced many pedal lines and early multi-effect devices, like the "944 Chain-Reaction" and digital delays like the now sought-after PDS series. The '70s and early '80s 200, 400 and 600 series of stompboxes have become very collectable. '70s gray "DOD Overdrive Preamp/250"s with LM741 op-amps fetch premium prices with collectors, with the yellow early '80s 250s not far behind. Later '90s DOD pedals have also become collectors items like the "Gonkulator", "Grind", "Buzz Box", "Meat Box", "Vibro Thang", and "Big Pig Fat" Distortion.
In early 2010 Harman employee Tom Cram personally began a clandestine skunkworks project to revive DOD. This resulted in the prototypes for what would be the new DOD 250, 201, and an unidentified third red pedal. This skunkworks project was unknown to Harman and only became official after Mr. Cram showed his completed prototypes. Mr. Cram has subsequently become the marketing manager for DigiTech/DOD and continues to work on new DigiTech and DOD pedals.
On September 16, 2013, DOD returned with updated versions of the venerable "Overdrive Preamp/250", and "Phasor/201". Both feature true bypass, blue LEDs, modern power jack, lighter aluminum chassis, two tone flat-black and metal-flake paint jobs. The 2013 250 also features an LM741 op-amp to replicate the sounds of the original 250. In 2014 three more updated DOD pedals were released, the "BIFET Boost 410", and the "Envelope Filter 440", and the "Electro-Optical Compressor 280". The 410 features a new buffer on/off toggle and the 440 features an up/down voicing toggle, and the 280 circuit is untouched except for the addition of true bypass, LED, and modern PSU jack. All feature true bypass, blue LEDs, modern power jack, lighter aluminum chassis, two tone flat-black and metal-flake paint jobs.
