I like the Shure SM57 ... placed about dead center about 5 inches away from the center of an EVM12L speaker ... but turned away from the center toward the middle of the actual speaker surface. The center is generally too harsh. I run the microphone into a pre-amp and then tap the signal directly into the M-Audio 24/96 sound card in my PC. I run the pre-amp "dry" with very little reverb/effects then add it in the recording software. What do others do? Anyone not use mics? Something else? This is some good information I googled off about.com about mic placement on guitars ... just a good basic reference. Micing a Guitar Amp One of the most common situations in a recording studio - or live sound situation - is micing an electric guitar amp. You'll find a variety of amps and sounds - almost as many different amps and sounds as there are guitarists - and it's really simple to get a decent sound. The biggest problem with many amateur guitarists is poor tone, and that's the first thing you might want to correct before you start placing a microphone for recording or live sound reinforcement. Take a listen to your amp and guitar combination on microphone-level -- that is, where the microphone would be placed when recording. Adjust your tone so that you're happy with it, but remember one thing: the low-end will be increased with a microphone placed close to the source, something called proximity effect. Selecting The Microphone Your preferred microphone for this will be a dynamic microphone for it's ability to withstand high volumes. The preferred microphone for may is the Shure SM57, but the Sennheiser E609 is also a popular choice, and is my preferred microphone for guitar amps. You can also try a condenser microphone if you're playing softer music - jazz in particular. My favorite condenser microphone for guitar amps is the AKG Solid Tube, but depending on your preferences and needs you may find something different works best. Placing The Mic The first thing to understand in microphone placement on guitar amps is that the sound doesn't resonate from the center of the cone; it comes from the off-axis - or "off center" area. How you position the microphone is really up to you and what you want your recording to sound like. If you're wanting a louder, more treble-filled sound, you want to place your microphone towards the center cone. If you want more of a warm tone, start moving out towards the center. You might also try using two microphones on your amp - one close up and one farther back. You also need to remember, when running your amp in a recording situation, recording it at the highest volume possible while still achieving your desired "tone" is really recommended.
