    Does anyone know any, or have links to DIY Dyna Comp mods?
    I'm looking for info on how to do these mods/parts etc., not where to buy a kit.
    Thanks

    From what I understand, the newer model dynacomps are contructed with SMD components, making them incredibly difficult, if not impossible for the average person to modify.

    If you have an older model do a google search for Dynecomp mods there is a ton of info out there.

    Geofex, General Guitar Gadgets, Diystompboxes forum are all good places to start.

    Maybe I'm missing them but my searches have come up empty.
    I don't have any trouble finding people selling mod services, however. :)

    I'm technically proficient enough to do any mods.
    Particularly,I'm interested in the T-von mod. A friend of mine sent his in and had it dome and I really like the way it sounds.

    In terms of mods, there is a resistor that can be changed to modify the release time. This mod is often called attack, though:confused:. You can put a pot or switch to get different settings. I haven't tried that one, myself.

    What I noticed in my 1979 Dynacomp after I got it working was that it had a certain harshness and distortion. There were a lot of poor quality caps (tantalum and ceramic) which I replaced with film/polystyrene. I also added more filtering, which is what the Ross compressor does to the Dynacomp circuit. I actually used 33 mfd caps which I saw on the Way Huge Ross clone. Both these changes made it sound a lot better and eliminated the harshness and distortion.

    Of course, I made it true bypass and added an LED!

    So, you might experiment a bit with the coupling caps and try to get a Ross schematic to try some of those ideas.

    Because I'd rather drive all the way across town to buy the parts for $4 just to prove a point. ;)

    Thanks for the tips and links!
    I'll chew on those for a while.
