Anyone have a schematic for Danelectro Fab Overdrive?

I got this pedal as a freebie when I ordered something else and it's a bit weak on the high end of the tone control. I looked for a while but never found the schemo for this model-and its surface mount for the most part-but we have microscopes at work I can use for S.M. soldering.
My BOSS Blues Driver has much more tone control, but I'd rather take this Fab pedal out to gig and keep the Boss in good shape....any help is appreciated!

I adjusted the capacitance down to a lower value and got quite a bit more high end out of it, replaced the 223 with a 103. I might go a little lower but for now it's doing a lot better.
