True Bypass Looper with ABY

[N64Lover]

Hi everyone, I am wanting to build this Beavis Audio looper pedal but with a twist. I also need a pedal for teaching, which will allow me to use two basses into one amp simultaneously.

Is it possible for me to add a switch to the input to route it straight to the output and bypass the 3DPT switch? In that way I could use the return as a second input?

Or is there a better way to do it? I am not good coming up with circuits!

For a 2 in one, could you just buy a reverse splitter cord, 2 mono inputs into one mono output I to an amp? It's not as fun but it should get the job done.

Put the A/B switch  in front http://www.beavisaudio.com/projects/Looper-Switcher/index.htm connect your input to the input of the A/B switch. So you have two inputs (A and B becomes the input and 1 output) with a switchable loop
