Overdubbing Guitars With A Bullet
“I’ve got a technique I use when I overdub guitars. First, get a white noise tone generator (or just a loud hum from the guitar amp). Then send the microphone feed to the mixing desk and CRANK it through the headphones.
"Next, you’ll want to carefully put the headphones on and — as you move the mic around — you’ll be able to hear the high and low frequencies change as you get phasing anomalies. Warning: Make sure the assistant engineer keeps the guitarist away, so he doesn’t plug in and blow your ears out! I usually end up placing the mic where it seems like I can hear the maximum high and low end responses. When you are finally ready to overdub the guitar parts, if it still doesn’t sound good, then to hell with it . . . forget everything I just told you, and place the mic where it looks cool!”
