Amp selection pedal possibly?

[einziger76]

I am wanting to build a pedal to do the following: have one input and two outputs along with two single pole double throw switches if it will work.  What I am wanting to do is leave the input jack with a hot wire going to the center pole on the first switch, on the left pole have two hots leaving going to two different outputs.  Then on the right pole have one hot going to the center pole of the second switch.  On the left pole of the second switch have a hot going to one of the output jacks and and the right pole going to the other out put jack.  In my theory this will allow you to run two different amps at the same time or click the first switch to allow you to select amp A or B via the second switch.  Should this work?   I am sure if it will I would need to add resistors and if so can anyone help with any tips or advice on what resistors to use?  Thanks for any help! 
I have a drawing of what I am wanting to do but how do I add it to this post?

Its called an A B Y splitter. I made one years ago and it worked great. I did however use one switch for each amp out, no leds or anything just bare bones.
No resistors necessary.

You were able to run both amps then switch to running each amp individually?  That's why I thought it would take two switches.  If you clicked switched 1 it would change from running both amps on one post of the switch then the other post would go to switch 2.  Switch 2 would allow you to toggle between amp A or amp B.  So my theory goes.  Lol.

I searched ABY guitar pedals and there seems to be one that does what I am talking about called a Radial BigShot ABY.  It has other switches for something but it is what I amp trying to basically achieve.  First switch both, second switch toggle A or B.

All A/B/Y boxes work that way. The only question is do you want isolated outputs or not.

What is an isolate output?  I've made one pedal.  An mxr d+.  So I don't know a whole lot.   The way I have it drawn up it looks like it could back feed when running a single via the toggle because I have two hot wires going to out our a and b from the both switch as well as the a and b toggle.  This is why I thought a resistor or something may would not allow back feed.  I would up load a picture of what I have drawn but have no idea how to upload on the forum.

Just a note that the Radial Bigshot A/B/Y is fully passive (no battery or power) with a caveat that if the isolation transformer is used, there will be some tone loss. You will pay more for an active model with a transformer isolated output but the tone loss will be much less and in the case of the one I built, almost imperceptible. The transformer isolated output prevents ground loops that cause hum between different amps and, in my opinion, pretty much necessary as you will have hum in most cases where you drive 2 amps. I don't agree with Radial's reasoning that a buffer (which will extend the frequency range of the isolated output) tends to introduce tone suck, given the selection of precision/low noise opamps out there today.
If you search here for Hum Free A/B/Y you will find some good info to build these simple devices, as the buffer and summing circuits require few components. The commercial offerings are there but a bit pricey.

I just used wire in between the switches and jacks. Each switch ran an amp basically. Worked like a charm with a Line 6 hd 147 and marshall jcm 2000 tsl. I have since got rid of the marshall and down the road I got a genz benz el diablo 100 but i experienced grounding issues (the genz was noisy) but it happened with my wireless rig too.

The transformers are there to isolate the amplifiers' grounds, not necessarily the guitar's. So if there is a loop a wireless wouldn't help, unless it's from the splitter to an amp (not from the guitar to the splitter).
