Simple ABY question

[daleykd]

Is there a standard schematic out there for an ABY switch where it's not the "A or B" + "A and B" switch?

I'd prefer it if the first DPDT turned on/off the A channel and the second DPDT turned on/off the B channel.  Then, if I wanted both, I manually click both switches on.

I was going to build http://www.generalguitargadgets.com/projects/15-boostersrouters/16-amp-aby-switcher-box, but then I realized the switches didn't do what I would prefer.

Thanks in advance,
Kyle

What you describe is just two true bypass switches in the same box.

But would that work if both A and B are on?  I figured I'd need some form of transformer so that when both A and B are on, I'd be safe.

I think I don't understand what you want. In series setups, it does exactly what you said.

If you want A and B in parallel, you can simply add them in a pair of resistors to the output jack. In most cases, they'd be OK without the resistor.

What two things do you want to do this with?  Why would you need a transformer??

You should define what it is you want to accomplish, Daley - at least enough for us to see the idea...do you want to have two effects, sometimes you use one, sometimes the other, and sometimes ONE BEFORE THE OTHER, BOTH ON?

Or the above, but BOTH IN PARALLEL WHEN BOTH ON?

If it's the first, series, case, then what R.G. said is how it is...two true-bypass switches, nothing more.

If you are doing something odd, like a parallel rig, you'd need to blend the two.

Info, please?  Where there's a will, there's a way, and you'll find it here )   If it easiest to make a flowchart of little black boxes if things are getting complicated on me.

Since I haven't had a chance this week to draw a diagram, I'll try to do it with text.

Ideally, I'm thinking the purpose is for me to have two amps.  Amp A will be on most of the time, and maybe I want Amp B on at the same time as Amp A for a bit.  Then, maybe I want Amp B only.  Then, when the show is over, I want it to work as a kill, so I turn off both.

Each Amp (output) has its own DPDT and LED.

I guess after thinking about it for a week, there is no need for transformers (derp).  However, I'm assuming I need some form of passive mixing (a resistor or so)?

The idea is the following four options:
1. A only
2. B only
3. A and B
4. None.
