Re: Looking for a Detailed Explanation of "Re-amping"
As everyone else said, it's recording a DI track from the guitar, and playing it back through a reamp box (a reverse DI of sorts), back into the amp.
It allows you to nail performances perfectly and deal with getting the perfect tone later, as well as some other cool things like blending 2 different amp tones from one performance.
The thing I wonder about it is that I know through different amps I play differently to achieve a certain effect. Some of it is speed, some is dynamics, but if I'm listening to myself play through a modified Blues Junior I'm going to play to the amp and its strengths and try and emphasize that. if you flew the same performance to a different amp I tend to think it wouldn't6 be as good because I'm catering the performance to something entirely different.
That's the only real problem with reamping, one that I've been working on solving for myself.
If you're monitoring your playing through a POD, it's going to lack all kinds of feel and vibe a tube amp will offer - it's the quickest way of turning a Mesa or a Peavey into an overpriced POD.
But yes, you're playing will definitely change based on the amp, which is why it's best to monitor with the amp you'll use later, albeit maybe at a lower volume, or with a different tone than you may want on the final mix.
It's a lifesaver when you track through something only to realize that the tone sounds overgained and muddy when everything comes into play, or the texture is all wrong, or it doesn't gel with the rest of the mix.
The most obvious solution is just to track it with the ideal tone, but time and volume restraints often prevent this.
