FX signal mixer with unaffected dry through

[Francish]

Hello guys,
I'm trying to find out how to do the following:

I have two signals coming from an FX-pedal (dry signal + FX only) and want to make the FX level mixable without affecting the dry. I was thinking about recreating the ouput section of one of the many parallel looper designs out there. But all the schematics I found feature a pot to dial in the amount of the dry signal. Would just removing this pot work?
Also the idea is to install a switch which bypasses the pot that controls the wet signal entirely to have two different levels of effects level.

So could I just recreate the output section of e.g. this,: http://tagboardeffects.blogspot.de/2010/11/jfet-parallel-looper.html
with only two channels, remove one of the pots and install a SPDT to bypass the other one?

Thanks for any advice,

Francis

Yes, I'd have thought it should work just how you describe it.

The RHS of that circuit is just a passive mixer followed by a JFET buffer. As you say, reduce it to two channels, remove the pot from the dry channel, and add a SPST to bypass the pot for the wet channel. Then you can have full FX signal, or pot level fx signal at the flick of a switch.
