Hello all,
Here are some pictures of my first ever DIY pedal project completed in May 2010. They are exact 'circuit' clones of a circa 1979 'gray spec' DOD 250 Preamp Overdrive. The homemade etched and electroplated PCB is my own custom ExpressPCB layout (did not use their board service) after many months of research on the original pedal and learning how to DIY at the same time. I also used IDmark aluminum plating for the top etched 'reverse schemtic' graphic and labeling. I call this clone my Neo-Classic 741 Overdrive:

My 1st build housed in unfinished aluminum Hammond 1590B - owned by neoclassical guitarist Dean Cascione. Listen to this instrumental cover of 'Never More' played by neoclassical guitarist Dean Cascione that he contributed for the 'Magic - A Tribute To Ronnie James Dio' charity album using his own Neo-Classic 741 Overdrive that I built for him (pictured above) to give you a feel of what it sounds like on a professional studio recording:

Dean calls this his main "Grail Tone" overdrive for recording all guitar leads on his 2nd album called 'Neoclassical Fire' due out this Fall 2010 and he is promising a Neo-Classic 741 Overdrive video demo review and special guitar lesson coming soon.

2nd build housed in Black Powder Coated Hammond 1590B - my personal use copy.

Experimenting with this 1979 vintage era RCA 741 metal can op amp that I added to my own personal Neo-Classical 741 Overdrive, but don't be fooled by mythical 'NOS' parts like this. They are only good for cosmetic reasons (as a historical era dated part in my case) and really don't sound any different than modern equivalents do.
Watch this video test demo with bluesy guitar playing by my wife's cousin Jim McDonough with his Fender 1965 Deluxe Amp and 1957 reissue American Stratocaster. I hope to make my own clips soon in the neo-classic rock style with my Strat and Marshall amp, so in the meantime sorry for the poor audio quality here. My little digital camera was probably too close to his loud tube amp:

Well these are the only two I've built so far. Currently I'm working on making a clone of a 1977 MXR Dyna Comp (to hopefully improve my sustain at low practice volumes) again with my own PCB layout version under development.
