Modding my Telefunken echomixer plse advice

[jans]

Hi all,
I want to be able to switch off the direct sound from the echo mixer. Also, i want to route output channel b into c (through a switch), so i can really drive it. I attached the schematics, can someone advice on how to do this?
my guesses:
1. dry off switch: place a switch after C12?

2. reroute output to input: route the output of w7 to w11?

is it as simple as that?

thanks!

Yes.

Did you cut the connection from w7 to the mainoutput when routing it to w11?
...
Btw. i'll try to change some capacitor values to make it a bit more suitable for bass sounds.
It has a rolloff at around 120Hz and cuts quiet some bass.
...and i am thinking of doing the opposite for the reverb path.

Did the "output to input mod" work? Isn't it better to cut and take the signal after the coupling cap C3?

In case somebody is still into it. It all worked out perfectly beautiful. I add my documentation.

EDIT: I am more a tube/valve guy. I have the feel that the daisy chain mod messes up the phase. But it creates lovely results anyways.
EDIT v2: I think I was right. If I send out reverb vom Ch B AND C, the summed signal that is going into the reverb is out out of phase. But playing around with different amounts of sends is bringing interesting results.

You add a very simple circuit with a TL072 OPamp to reverse the polarity of one of them
