Hey all,

I'm still a huge noob, and I'm looking for some input on the following switch wiring:



I want it to accomplish the following:

OFF
IN -> BIN
BOUT -> OUT
LED -> Float

ON
BIN -> Ground
LED -> Ground
OUT -> Ground

I believe this wiring accomplishes this, but I'm a bit worried about the BIN and OUT being connected in the ON position, and then connected to ground. Is this a problem at all?

What's the function of the switch? It's slightly confusing on its own as switching it "on" disables BIN and OUT by grounding them and leaves IN and BOUT not connected to anything.
Bringing you yesterday's technology tomorrow.

It's a mute switch =). BIN and BOUT is a line to a PCB buffer. When the mute switch is engaged then the buffer in and the OUT (output jack tip) would be grounded

why not simply connect the input to ground and use a dpdt? I don't see why the buffer even needs to be wired to the switch.

Um, the point of this switch is to go into a pedal that functions as a true bypass loop + mute switch and a line driver. This pedal goes last in my chain because I was looking for something to replace my tone sucking volume pedal for guitar switches and drive long cable runs at the same time. I figured I could build a TBLoop, stick my delays inside it, and add a line driver buffer and a mute switch and get a small swiss army knife EOTL pedal.

I could indeed simply connect the output of the TB loop switch to the input of the buffer, and then toss the buffer's output to a DPDT switch and do as you say, but I was wondering if I gain anything from grounding the output of the buffer too.

Again, I'm a noob at this so I'm looking for whatever advice/experience I can find ;). I'm still in design stages because Small Bear ships incredibly slow. Else I would just be experimenting with all of these ideas.

Yeah, I stick with what I said. I don't see what grounding the buffer too would accomplish. Muted is muted, the buffer is not a high gain circuit.
I don't understand how the delay figures into this pedal. You said 1st that it's a "true bypass loop + mute switch and a line driver" then talk about  sticking your delays in a loop. Are we talking about a loop just for the delay seperate from this pedal?
