I bought a cheap Kokko compressor because it was only like 25 bucks shipped, but Im wanting to get more gain out of it as its not really enough to use as a booster. Is this possible? Is it a matter of tweaking some resistor values or something?

Maybe but unlikely. Chances are it's not worth it (trade offs like increased noise, and/or the increased gain will be minimal). Also it's probably all SMD stuff; not much room to add things and a pain to deal with, and risky without some specialised tools..

Much easier to just build a simple boost pedal to use after it, e.g.:



2 caps, 1 chip, and a pot. There are other simple boost circuits out there using discrete transistors, but they use a few more parts (not that much necessarily; but this thing is dead simple).

It looks like it's probably a clone/derivative of the Dynacomp. Were it not a mini-pedal, I might have some modding advice. But it's likely using surface-mount components, which complicates mods substantially. First, you need a fine tip iron. Second, one risks sweating components out of place with too much heat. Third, boards using surface-mount to cram everything into mini enclosures often use double-sided boards. This often makes it very difficult to identify paths and key components. Fourth, if you can actually ready the values of the resistors, even with a magnifying glass, you're a better man than I.

While not a cakewalk, having a schematic and a component-layout diagram would make things much easier and feasible. But I wouldn't touch it if I were you. Make or buy a clean booster instead. I think things will work out better for you that way.

And, as an aside, some compressor designs provide more output level when compression is turned up, while others provide more potential output when compression is turned down. Play around with yours and see which of those it is.

It has more drive when turned up but it's kinda a cheesy sounding Comp compared to the diamond I had before.

It sounds perfectly normal to me. Many compressors lose a bit of high-end as a normal part of how they work. This is why more and more compressors are including a Blend/Mix control, to bring in some of the uncompressed signal that still has all the high end.
