Help building an A/B/Y box ... buffered ?

[Derringer]

I have two identical amps and a 4X12 cab that I'll wire for stereo operation.

I want to run one amp with a home built fuzz and the other amp with my normal crunch/overdrive settings.

I'm assuming that I would need some kind of buffer in the A/B/Y box so that an equal amount of signal is sent through both legs?


Recommendations?

Tips?

Can anyone point me in the direction of an existing schematic?

Thanks!
