Those IC should be ok.
I checked the layout, but I didn't find anything wrong, looking at the schematic.
But maybe I found what's wrong.
if you have the original Boss FA-1 transistor 2SK246-GR (or similar pinout DGS) this layout I guess it will work.

Else you have to try to invert the pin S and G.



I hope that's it. You should try, at least to know if all the rest work.

Else...
Did you check everything in your build?
Maybe some pictures can help us to check it out together.
Check if wires are in the right spot, like the all the caps and resistors. If you have doubt about the the position on the board try to look at the schematic.
Count the cut tracks and check if the strip are really interrupted.
Check the orientation of the electrolytic caps and  the 1N5817 diodes.
Count the jumpers.
Tell us the IC and the transistor voltage.

Anyway, I could re-drawn the layout with the right pinout transistor, but maybe you need to build it again, because you could make your board some mess, if you decide to adjust it.
