Dual micing a guitar amp

Last couple of weeks, I have been working with an interesting blues/roots rock "band" that consists of two players, the singer guitarist and an upright bass who plays a kick drum at the same time.

The guitarist plays slide on either a semi-electric kay straight into a small tube combo amp, or a resonator or an acoustic through a pedal board/di setup.

One Saturday, I arrive at the venue to find out the bassist has gone on a trip with another band he plays in and the guitarist/singer is going to play solo. We set him up to play the kick and high hat with his feet while he plays guitar with his hands.

In order to create some width/depth to the mix I choose to double mic the guitar amp by mixing a dynamic mic with a LDC. Each mic was slightly panned away from each other and set at slightly different distances from the speaker. The mains in the room were 90 degree boxes stacked SL and SR and only about 16 feet from each other, so most of the room did have some sort of stereo coverage.

The double mic worked fantastic, and had a great tone. The band following use used the same amp at basically the same level through the channel with the dynamic mic on basically the same eq settings and had nowhere near the same impact/depth. The end result was a mix that had the same size as a five piece band but with much more clarity.

I am pretty sure I picked up the idea from a Dave Rat blog/article but I am never sure just what is floating around in the back of my brain. I don't work with drums or electric guitars a lot, but when I do it is neat to see how these "big stage" ideas still work in smaller venues, and it is really nice to see how they can set one "band" apart from the rest of the lineup in a 4 band bill.

Lately I've been using a 57's and "Fatheads" (ribbons) panned at 9 and 3 o'clock respectfully with pretty good results. AT 4050's work nice too. It all depends on the the player's tone YMMV
Peace

My favourite is to use the AT AE 2500 dual-element mic on guitar and use the "bite" of the dynamic to "cut through" and use the warmer condenser sound to bring up on solos without sounding too harsh. I mix and match as needed throughout the show sometimes. Sometimes a slight pan, sometimes not.

Using two separate mics works fine, too, but I would be weary of having different distances between tha amp and the two mics.

A Royer ribbon (122?) and a Shure SM57 seems to be the dream combo for many guitarists.
 
Re: Dual micing a guitar amp

Every time I try two mics, by the time I have each EQ'd such that I like the tone, when I put them together they sound so similar that there's nothing to be gained by using two ;-(


What you could try is to gang the EQ's of the two mics on a digital mixer and start out with both mics pulled up to the same setting in the mix with flat EQs, and then EQ them as one to give "one sound" together. That way, your "base setting" will include the sum of both mics in the mix, but individually they'll still sound different - which can be a cool little tool to bring up on solos or for cover bands that need "something different" on a song, etc.

I don't think the difference between the distances is that critical as it is basically less than an inch and mostly due to the placement of the element in the mic body.

I did not use a lot of eq, just basically let the character of the amp and mics show through, but I also had the advantage of a totally stripped down mix with nothing else competing for the same space.

Hi Everyone,
The best guitar sound of all time (including all the A player nationals I have worked with) for me was a triple cabinet triple mic setup. First and foremost a great local player with very low stage volume and a great local band. Center cabinet dry, panned center. Left cabinet effects only, pitch tuned down .99 full left pan. Right cabinet effects only, pitch tuned up 1.01 full right pan. He used mostly chorus with a small reverb added at times but his effects were always on. I was FOH that night and I used SM57's center and right and a Senn e609 left. All house EQ flat. All house effects on guitar off. Unbelievable! The guitar filled up every sonic inch of space but stepped on absolutely nothing. Crystal clear vocals drums and bass. Numerous positive comments on "My Mix" but it was actually the guitarist sound "faders up and flat" that made it what it was. Just food for thought for everyone.

+1, though I'm using the ATM250DE.

Sounds like what I used to do for Ian Thornleys setup. First time I mixed ears for him, he made it 3 bars before stopping and asking what he was listening to. My reply was 'Your guitar rig'. He was dumbfounded for way too long for a guitar player/touring artist of that level should be.

Hi Brad,
Ian is a super talented player for sure. Great singer too! Did you do that at the board with effects or did he have his rig set up that way and you did the mic and pan thing? I was just curious.
