Truebypassing an Electric Mistress

Hi guys.

I know there are a lot of topics about this flanger... but I want to clarify one thing: I used the GGG schematic and layout. I assume this box is not true bypass, right?
The question is:
What do I need to do to make the bypass mod?... I mean, the R19 resistor is there for a reason... Will I have a volume drop?? If yes, what do I have to mod in this schematic to avoid it?

I think this topic could be useful for a lot of newbies like me. Thanks in advance

right: the GGG-missus is not TB...

Thanks!! Is what I suposed...
What should I have to do?

First, read "The Technology of Bypasses" at GEO, http://www.geofex.com. It is likely that after you read that, you'll know what to do.

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.

Hi R.G.
I can understand (more or less) the Tecnology of Bypasses (anyway, thanks because the link... there are a lot of things to learn from these articles), but the point is that I cannot understand how the layout has been done in front the scheme. (In the layout we have a DPDT for the ON/OFF, but a simple switch is shown in the schematic)
I'm afraid I'm not shure where are the "in" and the "out" in the layout...
Perhaps I'm magnifying a little bit a very small problem... thanks again to all of you

Hi again. I've truebypassed it by supressing the 180Ohms Resistor. It seems all OK, but I got a noticeable volume diference between ON and OFF stautus...
What do you think??
