what i want is a simple a/b switch that switches via trs rather than a stomp switch.  no hum would be nice.  no led is necessary.  i have the input jack, both output jacks, the trs jack, and the chassis.  what else do i need?  can anyone give me a simple schematic for this?
thanks.

Check out this one:

Follow the A/B switch link.


I think that was what you wanted - and this is a good implementation - I like my version of this in an electrical box.

I'm not sure I understand the TRS part -- you want to switch by way of TRS rather than a stomp?  Can you explain the switching mechanism a bit.

As for the fulltone plan -- since that only switches between inputs (or outputs), will it be free from the popping that accompanies passive loopers?

i have a midi switcher using that uses trs to switch amp channels, etc.  no popping would be great.  is it simple to replace a stomp switch w/ a trs jack?

The trouble with "switching" using a TRS jack is that whatever amp is connected to the Ring will be dead quiet when the plug is all the way in (Tip active) but the amp connected to the Tip will hiss when the plug is halfway in (Ring active).
What does this button do?

hi,

can you post how you wired it for two inputs into one output?
thanks,
paul.
