You can monitor the original dry signal so it doesn't affect your playing. Guitars have a high impedance signal, and on the contrary, line inputs have low impedance, which means that if youd connect guitar straight into the line input.
With its high dynamic range, the DI will capture. If you want to record the dry and re-amped signals at the same time, just record them on two different tracks. The Joyo JDI48 is a 48V phantom powered, active DI and re-amping box.
You can get latency pretty low, but not zero. One important thing to note is reamping is not exclusive to only guitars. When this is achieved, you don’t need to re-record the audio all over again. Doing this can help you preserve the sound output from the guitar.
On a typical re-amp signal path, the signal is going through ADA conversion twice, and that takes time. How To Reamp Guitars with a DI Box You can do this by positioning your DI Box in the middle of your guitar and your amp or pedals. The dry track will play back and the re-amped track will record a few millisecond later You can adjust the timing later by moving the re-amped waveform in the editor to align with the dry track (if there is a reason to align the two tracks, if for some reason the two have to play together). The question that comes to mind, is why are you re-amping? If you're recording live with the amp mic as a source, why not just plug the guitar into the amp and record it? What's the point of setting up a re-amping signal path? If you're recording dry through a DI, then re-amping so you can try out various settings and fine tune, again just go out through the interface to the amp, and back in from a mic through the interface, arm a track, and hit record.
