DOD 250 ‘Grey’
A clone of the DOD 250 Overdrive Preamp built to 1979 ‘grey’ specs. The knobs control Volume and Drive. The toggle can switch between the two stock silicon diodes (1N4148) clipping and a choice of other clipping options (asymmetrical, germanium, LEDs etc.) or it can be fitted with a tone switch. Also great on bass or for pushing a tube amp into overdrive.
Solidly built with high quality parts, Panasonic and Wima caps, metal film resistors, LM741 chip as in original, beveled 3mm LED, Alpha pots, enclosed Switchcraft jacks, lock washers on all jacks, pots and switches.
True-bypass switching with grounded input and power filtering and can be powered by a standard 9v Boss-style power supply or 9v battery.
DOD 250 Grey with a toggle switch for treble cut and boost.
Price: €85.00

It can also be built with a range of modifications as seen in the above pic.
Here the top toggle switches the stock setting of the high-pass filter at the input, allowing either more bass through the circuit or turning it into a treble booster. The lower toggle lowers the bass roll-off going to the clipping section, whereby the lower frequencies will produce more clipping and a beefier sound.
The second footswitch engages an alternative clipping section using germanium diodes. An internal trimmer can lower the level of the silicon clipping section to match the germaniums, so there’s no volume drop when the germaniums are engaged or you can set the germanium clipping to be slightly louder for emphasis or solos etc. The germaniums have a thicker, ‘hairier’ sound than the more open sounding silicons as they clip at a lower level, which means you can set the Drive knob to just below clipping the silicons for a clean sound, then switch to clipped germanium. Different clipping options like silicon diodes or LEDs could also be used for the switch.
