Hi there, and Thanks a lot for layout and schematic, Manfred!!

Two things I would like to ask:
1st- The layout says IC-pin5 4k7 to virtual ground, schematic says 100k. What´s right?
2nd- Between IC-pin 2 and 1 layout says 100k, schematic 10k. Again, what´s right?

Thanks a lot again, great job!

I love the Redson effects (as well as Rolling, which is the same, i guess), thank you Manfred !
I would be curious to know how it sounds ?

I have been selling the Overdrive for some time but as far as I can remember it was a good sounding mild Overdrive.
Maybe someone else has the original or has built a clone and can tell us more.
