recording guitar

Re: recording guitar

Experimenting is key! The 3:1 Rule for phase is a good starting point, but you need to use your ears, this drastically changed my recorded guitar tones. Take 2 mics (bonus if they're two of the same, it just helps for this purpose) and throw them up as close together as possible. Now send a DI loop back and slowly pull the second mic back. Now listen back, you'll hear it. An inch makes a difference, and not all mics have their capsule the same distance from the outside of the mic, therefore it is damn near impossible to achieve perfect phase with a measuring tape and 3:1. Like I said, good starting point. And you are introducing even more complications when micing from the rear. I would (normally) reverse the polarity on my mic-pre much like for a bottom snare mic in that case as well.

And yes, often guys would use multiple mics, but they would also bus them down while tracking, there may be 5 mics up but you may only be hearing 3 of them, with one dominating and 2 other filling in whats missing here and there. I'm often like this, I have 4 up, but might onyl use 2, and usually its not a 50:50 blend. More a 70:30 type thing.

I could never be 100% sure which mic/pre combo would sound best and have the ideal EQ curve for the various guitar/amp combos each time, so I tend to always put 2-4 mics on a cab through various pres, record the multiple tracks and just choose the 1 track that sounded best in the mix later. Saved a hell of a lot of time getting a good recording of a good performance.

Sometimes, once all the other parts were in place (bass, drums, etc.), my first choice for the guitar track didn't sound so good any more and I switched to a different track. Glad I had the other tracks to choose from to fix the problem without re-recording. But I only use 1 of the tracks in the end. The whole point was to be expedient and not loose a performance. I'd hate to have to re-record a performance, which will never be the same twice, just to correct a mix / EQ issue between a mic and pre.

I would never mic behind a cab. Cabs weren't designed to put out good sound from the back. There's nothing good back there to pick up.

A room mic is a different matter. A room mic mixed in at a low volume can make the one main track sound natural, like being there. But it may require some strategic panning to give the track life, keep the detail and not create sonic mud.
