I need some help here. I have a volume pedal that I have 4 jacks in- 1 In, 1 Out, 1 Tuner Out, and the 4th jack I want to be either In or Out depending on the SPDT switch position. Below is the wiring diagram that I've been working with however it simply bypasses the potentiometer for the In as diagrammed and I'm stumped and could use some help from one of you learned electronics gurus  . I want it to remain passive and am trying not to degrade the input signal when used for 2 inputs. Thanks in advance for the favor of your attention- Jim

| Quick question,Jim----what happens when you flip the switch the other way? |

| Jim, The diagram seems right (to me). is it possible that the switch is wired incorrectly? I just think that the diagram is correct for what you are wanting to do. I don't see why this doesn't work. I will be glad ho hear the result. Dale |

When you connect two guitars they will directly affect each other... on amps with two inputs, the inputs are separated by some resistors to attempt to keep the guitars from affecting each other... this doesn't work that well, but it's better than connecting them directly together.
So plug in two guitars... the active guitar will be loaded down by the non-active guitar. If they have volume controls, the control on one affects both... same for tone controls.
You would have to buffer the guitars to fix this... in effect, creating a mini-mic-mixer. Your best use of the SPDT switch would be to switch between the two inputs.
You might have chosen the wrong wiring for your switch... use an ohmmeter and verify that the switch is doing what you think it is.
