Most of you probably know about this already but if you are just starting out your own recordings and productions, here is a useful tip. A guitar produces a mono output, which isn't a problem at all. However, when you are recording a guitar driven song, with a strong riff, you want your guitar to stand out in the mix and make it sound fat and powerful, giving it a solid presence in your audio field. There are numerous ways to achieve this but a fast (and inexpensive) one can be easily done by just recording the same riff twice and hard panning both tracks, each to its own channel. This will require that you are very precise in your playing so that both guitars sound like it's just one, unless you actually want to create some harmonies, which can also provide you very neat stuff. This is particularly useful for bands with just one guitar player as it won't require you to have a second guitar player on stage to perform what you just recorded but will instead give you an immediate boost to the way your guitar fills the mix. Believe me, this improvement is immediately noticeable and might just transform a mediocre riff into a powerful rhythm guitar. Now, if you're thinking "why don't I just record it once, duplicate the track and pan them both", it won't work, the effect will be canceled and you'll notice no difference at all so, don't be lazy and really record it twice. This is just a basic step for creating huge sounding guitars, as compression, parallel compression and EQ step in afterwards to give it even more power but it's a fast and easy way to start improving your guitar recordings. If you are going to try this, let me know in the comments how it went.
