the layout plan for the G3 Rock was indeed incorrect, but this has been corrected some weeks ago. I‘ve also documented this on my website (in the modifications/G3 Rock section) to clarify that for all customers that received the old version of the documentation…
Thank you indeed this is how I did it, my G3 works fine already recording some music I really like it, it is perfect for my needs.
Thanks for getting back to me, I spotted but my layout is correct I was referring to the manual photo which shows C2 before R2.
I have mentioned above after looking that it would have made no difference even though is better to do it how you described
So we recommend to solder C2 generally between pin7 of V1a and ground (pin 9 of V1a).
In fact I was just trying to point out at the difference between photo and layout, I think the one I received was already corrected because it is showing it as you mentioned. But someone else didn't get my point
