DOD: 250
So by this stage, I think we can all assume that I’ll be the only one making this. I have a bunch of tin can LM741 opamps that I forgot about, so I thought why not… DOD 250 / DISTORTION + LAYOUT
DOD Compressor 280
Yet another compressor, this time an optical one. The specified vactrol is quite expensive and hard to get hold of nowadays but you can roll your own using a LDR with 1M dark resistance and green diffused LED. Demo by Ian!
DOD FX70C Corrosion
From America’s Pedal:DOD introduced the Corrosion distortion pedal (FX70C) in mid-1997. With basically the same circuit as the FX70 Metal X, the Corrosion featured a heavily oxidized metal finish and no paint except red (1997-98) or black (1999) graphics near the control knobs; the first version with red graphics appears to have been more rare. … Read more
DOD: 250 Overdrive Pre-amp
A nice simple one – the DOD 250, which is a Distortion + variant. Or is it the other way around? Either way, it’s a classic. DOD 250 OVERDRIVE PREAMP – VERO LAYOUT DOD 250 OVERDRIVE PREAMP – SCHEMATIC DOD 250 OVERDRIVE PREAMP – VIDEO DEMO
DOD FX33 Buzz Box
This one have been requested a few times. Factory schematic had a few bugs (as with most DODs) so this layout is based on the schematic by Griffin Fx for their Buzz King project.
DOD 210 FET Preamp
Here we have a small one, an old J FET booster. Polarity protection diode and power filter cap has been added and the 22k Drain resistor is replaced with 50k trimpot so we can socket and try out a wide range of J FETs.
