Technically, yes, this is possible via the AXE I/O, but guitar amplifiers, specifically Tube amplifiers will require a speaker cabinet connected. Without one connected you can damage your amplifier. This makes this difficult.
Using different Stomp FX which do not require speaker output would work well. Using Z-Tone and the different controls on Input 1 you should be able to get a proper level when doing so. This would be one of the biggest advantages of the AXE I/O.
While I can't say I've tried a pre-amp in this way, this should technically work just fine. As long as this doesn't require a physical output like a Tube head would, this should work just fine on the AXE I/O side. Do note, if this pre-amp sends a line level output, you would need to use an input on the back of the AXE I/O.
