Love my pod X3 and the plugin
All the guitars and bass were reamped with it on this album
Wow! Quite a sound!
I used the POD Farm plugin and got this (warning: it's thrash metal):http://www.archive.org/details/rlsm01ep
I used a kind of "reamping" to get the guitar feedback:http://flspectro.blogspot.com/2009/03/la-tecnologia-de-simulacro.html
I plugged the headphoes output from the interface to an amp and attached the speaker to the back of the guitar.
PC -> headphones out of the interface -> parametric eq to add a little resonance -> amp -> speaker -> strings ->pickup -> interface -> PC
So... back to the question: if you really want to reamp with the gear you have you can try to plug the headphone output of your gear to your amp's input and record the speaker output acoustically. Please check you don't have ground loops and DON'T SWITCH ON/OFF ANY PART OF THE CIRCUIT WHILE THE CABLE IT'S ATTACHED, I repeat: DON'T SWITCH ON/OFF ANY PART OF THE CIRCUIT WHILE THE CABLE IT'S ATTACHED. If you don't know what does it mean a ground loop
don't try it and go with the plugin alternative, it's easier and you will have greater control of the final result. Or follow the advice of sublamp and make a DI box with a real transformer
1. The setup I used worked because I used a solid state amp. If you use a valve amp you can have impedance missmatchs that can introduce unwanted noise to the signal if you use the headphone outputs.
2. Actually, since you got a POD X3, you got it real easy: use the X3 as a DI audio interface! That critter even has the right outputs to plug it directly to your amp. Just read the manual and set it up. Remember: record dry, playback dry, setup your amp tone, record.
