So I built one of these AB switches, but when I have it on the output , the other has a little bleed through.
I use it to go to an amp, and a tuner. I don't want the tuner in the circuit, hence the AB idea. But when it's on the tuner out, I can hear a little guitar through the amp. Any ideas why?

I'm not sure why there's some bleed through, but if you make it true bypass with a 3PDT, I think that'd probably fix it.

actually, this is supposed to be true bypass

Leakage via the switch, noisy wiring? Did you use shielded cable? I had a cheapo Carvin amp switch and it was noisy. I went with shielded cable to eliminate most of the bleed. Didn't get it all though. Eventually bought a Radial unit. Solved the problem.
Most good switchng units have buffered I/O. Try shielded cable.

Bah, it was a flaw in the diagram design. I went with the simpler "eric johnson" wiring and it's noiseless:
