Sit Down, Shut Up, Play And Listen! Recording And Amp Setting Up Tip #8,768,541

Here's another microphone and cabinet setup in a different part of the room. Instead of attenuation of SPLs, this one is designed to smooth out the frequency response and maximize the clarity of the cab for a clean part.

This time I used the three tube traps with their diffusion surface facing either side of the speaker cabinet's edges, and one in the rear to also act as a diffuser. Because of the way the tube traps are designed, they both absorb excessive low frequencies, and diffuse the higher frequencies to smooth out the sound. The mic in front of the cab is an Audix i5 this time, for its slightly wider frequency response than a 57. It's hard to see in the pictures, but it's set a few inches further back than I normally do, again to smooth the response a little.

There's also a room mic that doesn't show in the picture, that I won't use very much of, just a touch to blend in with the track.

The picture shows how the cabinet is raised off the floor and tilted back using an Isoacoustics decoupler, sitting on top of an Auralex Great Gramma to further elevate it and prevent structure-borne acoustic issues. I can get pretty decent gig volumes this way, yet it remains distinct, not blaring, with a ton of very clear articulation. This is the product of a heck of a lot of trial and error (otherwise called "experimentation" ;) ).

The cabinet sits about 4.5 feet from the rear wall, and further from the side walls. It's elevated 9" off the ground in front, and 8" in the rear (the isoacoustics stand is tilted so the speakers point up a bit).

Haven't we all heard/said this ten zillion times:

"When I record, I can't get the tone I'm hearing when I play." Or "I just can't get the tone I'm hearing in my head."

Listen.

I record guitars nearly every day. Mine and session guys'. And here's a fact: if you're standing up and your guitar cab isn't at ear level you aren't hearing your tone at all. You're hearing the room. No matter what you think, what is really coming off your speaker cone is going to sound different than what you think you hear standing up.

Sound bounces around a room and in the course of that process, some of it is absorbed by the materials in the room, some is reflected around the room and comb-filtered, and some of it just echoes echoes echoes...but in any case, you're not hearing what your guitar and cabinet sound like. And you're certainly not hearing what the microphone hears.

Some here know I'm a believer in acoustic platforms, isolation risers, and acoustical treatment. But even with that, you're going to hear room. To understand what is actually coming off the guitar speaker cone, you have to be in the direct field of the cone. And guitar speaker cabs are beamy devices, especially in the high frequencies. So what you want to do is sit down, so that your ears are in the direct field, but far enough away that you won't go deaf (sound pressure level is reduced by about 6 db if you double the distance between yourself and the speaker). I find that if I'm seated about 8-10 feet away from the cab, and the cab is even as low as 6 inches from the floor, I'm hearing the direct sound of the speakers much better if I'm sitting with my ears in that direct field.

And here's the thing: It's the best way to hear your amp. Whether you're setting up pedals, or working with your amp controls, or wanting to hear what the microphone will pick up, this is the way to do it. Don't stand with your ears 4-5 feet above the level of where the speaker is aimed and think you're hearing it correctly. Even angling the cab, which is a good idea, and helps, isn't perfect if you're not in that direct field of the cone.

People in a studio often stand, and get what they think is the perfect tone, and then listen to playback where the mic is an inch from the speaker right on the cone, and they can't figure out what the heck happened. What happened was that they had absolutely no idea whatsoever what was coming out of that speaker cone.

And of course, if you're not in the direct field, you don't hear the high frequencies correctly, because they are more beamy than mids and lows. So you tend to crank the treble and the result sounds good standing up, but what is coming off the speaker is harsh, and sounds harsh to the mic - and to a live audience who are farther away from the cab than the player, and are in that direct field of the cone. So they plug their ears!

So...sit down, shut up, play yer guitar, and listen to the speaker, not the room. Then you can set everything up right.

I do this even to set up pedals, set my amp controls, etc. No surprises.
You
Merry Christmas
 
Great info in this thread, thanks for that! I totally agree with everything you said. It makes a huge difference where your ear is in relation to the speaker. I prefer to be as far from the amp as the room/stage allows, especially while standing, and now I know why :) !

Glad you found it useful!
 
Great advice. I was tired of the terrible recordings with my acoustic. I had a friend play it while I stood in different spots to find the best mic position for that guitar. Works.

What works even better for determining mic position is to have the friend play the guitar while you wear headphones, and move the mic around so you can hear exactly what the mic is picking up.

Because mics hear differently from your ears.

+1 (or really +1000!)

Problem I have is, I don't have a buddy to do this with at home, and have to play, put on headphones, and move mic around, all at the same time. Which stinks...

I have had the same issue since my son left for LA!

There are a few things I've done when I can't find anyone in the place to help out:

1. Record a direct feed and use a re-amping setup while I move the mic around. This works really well, but of course is a complete pain in the rear with lots of extra steps. Plus I have to replace the box I used to use because...you know...stuff stops working after many years.

2. Put the mic stand on a dolly board with wheels that I made for an old amp, and move it with my foot. Not a terrible way to go, but obviously less desirable than just having an assistant.

3. Beg my studio manager to come over and move the mic stand. Sometimes this actually happens.

Les, something just hit me. I have a Ditto Looper. That may be the perfect device for what we're talking about. Play a bit, some chords and a bit of lead, then hit the switch. Then set your guitar down, put the headphones on and go move the mic around. I don't know why I didn't think of this before. Some call me a genius. Ok, not really!

You know, that is a great idea! I have a looper on my Eventide H9. I'm going to try it!

You ARE a genius!
 
Seriously, Dream Theater Rules Rules!

This is the best idea I've seen for doing mic positioning when you're working alone I've seen in forever.

Dude is thinking outside the traditional engineer box, next he's going to invent an electric gizmo that lets you move the mic via thought waves.
 
LOL. I hope it helps Les. Necessity is the mother of invention, or Frank Zappa is. I can never keep that straight. :D

I'm working on the thought wave project. Still a work in progress. Right now, I'm trying to make your HX/DA amp come to my house. :rock:

I think it will work! You had to have talked with my wife, because she doesn't believe me when I tell her that I have flunked Mindreading 101 every time I have ever taken it. :vroam: [Ducking, runnin', and grinnin']

My wife can read my mind.

Either that or she can read the guilty look on my face.
