Reamping one performance into two different amps = phase issues?

A guitar amp isn't a linear-phase device so there will be some comb-filtering due to the differing tone-stack circuitry etc.
If you use different cabs you'll have to phase-align the mic's, which is a bit more hassle than using a pair of mic's on one cab.
Layering's cool when it works but sometimes it's a bitch to capture a good layered sound.

I never had success reamping with just one performance. Even after aligning and moving stuff around it never sounded right to me, just not layered to me. I guess it takes a really good ear because i'm surprised Machine from Lamb of God can quad track one performance and keep it from sounding phasey...

Ive tried reamping a the same part through a 6505 and a triple XXX and one is out of phase with the other each time. Its just to do with the design of the amps. Knowing this though its pretty each to flip the phase on one as it goes in.

Well, since the performance is already captured, it's pretty easy to solve. Just hit play, then move the mic 'til it doesn't sound out of phase. Once all is good, hit record.
the amps are never 180 degrees out of phase. simply flipping the switch wont work.
I have reamped one signal into two and even three amps with no issues. If you are having issues, try isolating each cab. But make sure you have a good reamp box, if your box is delaying one signal by a millisecond, you'll run into phase issues.
But the best way to solve the issue?? Zoom in your workstation and line em up! Bye Bye phase!

Sometimes amps are 180 degrees out of phase as well. A single triode tube amplifier stage inverts the signal 180 degrees, so if one amp has three gain stages and the other has four, they will be 180 degrees out of phase.
I understand your point and in theory it makes sense, but...
It is simply not possible for any two tube amps to ever be perfectly in phase. There is too much variation in circuit design, tube operation and voltage drift, just to name a few.

To get off on a tangent...
*dumb question alert*
If you record 2 amps through different cabs with seperate mics at the same time, would you face the same phase issues as using 1 DI performance to reamp through 2 different amps but using the same cab/mic setup?
I'm thinking not?

Using 1 DI performance to reamp through 2 different amps but using the same cab/mic setup will be in phase unless the mic is moved. It's really pretty obvious when it's out of phase, it pretty much cancels out and you don't hear much. Play around with the phase button on your DAW and you will see what I mean.
