Re: minor correction on GEO tremolo layout quote: "I think there's another error. The circuit shows c4 and c5 connect to r8 but on the layout and toner   pattern there is no connection. also the original article lists r4 as 12k and r6 as 1.2k ...what up wit dat?"     As to R4 and R6, the best I could read the original *was* 15K and 2.2K. You sure of the values???     You did find the only real error - Junction of C4 and C5 should connect to the collector of Q3. I have inserted the jumper that's supposed to be there, will update the on-line artwork.

Sweetfinger	On my printout I was pretty sure about the 12K and 1.2K and just to make sure, I looked at the parts list in the original article and sure enough- a 12 and 1.2 are listed.

R.G.	That's what I get for trying to eyeball the schematic instead of the parts list. I'll update the values on the layout. Anything else you've found, especially on the new, no-jumpers one?

R.G.	OK, check it now I started to just put in the missing jumper, and got carried away. I eliminated the jumpers, increased pad sizes, adjusted spacing for easier building, etc.

zgrav	oops. I was confusing your R8 and R10 with the 15K resistor on the EA schematic. Yes Yes Yes you had them correctly schemoed. sorry for the misinformed feedback.     I also appreciate your drawing talents and redraw to eliminate the R12 jumper.
