Dual Loopbox/TSA: Loop 1 Feedback bleeds into Loop 2?

[maximee]

Hi there...

First off I sorry for another TSA post...I tried to avoid this but I haven't found anything like this in the archives.

Here is what I built:



Since this is only a dual loop box I wanted every loop to be able to turn into a TSA by the switching a simple ON-ON switch. Therefore I connected:

send 1 to toggle switch to a 100k pot to return 1
send 2 to toggle switch to a 100k pot to return 2

The TSA/normal loop works very well. But the problem is:

When I have a Boss PH-2 Phaser in loop 1 (TSA mode) and switch to loop 2 I can still hear the PH-2 bleeding through...

How can this be possible? I've checked my wiring and it seems ok...

Should I shield the solder joints?

ok...i've checked my soldering and basically everything else...
i just don't get it...

i even left out the A/B LEDs...
it's not in an enclosure yet.
here is a detailed picture with all my modifications to it...i hope someone can help.



the sound of the inactive loop stops bleeding through when i ground its signal...i could do this for each loop with the free lugs on the left 3pdt...
but for this i would have to sacrifice my beautiful LEDs
