The AC/DC sound - guitars, amps, and mics
The Recording of Back in Black at Bahamas. tony plat, the recording engineer, writes
O.K. - the details about the recording of B in B are quite widely documented
but the basics are.
I do have various preferred microphones but will always vary my choices to suit
the room and the particular instruments.
The drums mics were O/H - U87 or U67, Snr top - KM86, Snr under - Shure SM57, Toms - Shure SM7,
Kick - U47, Hats AKG 414 or 451.
Gtrs - 1 x U87 & 1 x U67 on each
Bass - AKG D12 & DI
Room U87
Vocals U87
no compression on drums or gtrs
Can't remember vocal compressor
analogue 24track @ 30ips
MCI console
Tannoy monitors
and of course the most important components - AC/DC!
I know this sounds a bit obvious but really the gtr
sound comes from getting it right when it comes out of the amplifier and then
recording it properly. When you do that then the musician plays better because
they can hear the results of their efforts and then that makes you look good
because that makes it sound even better still. Choosing a good place in the
room helps and using good equipment (and applying some good old common sense)
plays a part.

got such great depth on the snare sound on that album. I read somewhere that
there were some delays and an eventide H910 involved. Would you feel
comfortable expanding on that topic a little? To be more
specific... What kind of settings did you generally use on those delays?
And how far down did you detune on the H910? (which I
assume was blended in with the original snare).
Thanks Tony!

[tony plat:] You are absolutely right! We fed a gated snare signal into an
H910 detuned to about 93 with the feedback and anti feedback up. This was a real pain as it would fail to trigger sometimes.
Yes it was just under the real snare. no other
harmonizer will work!! I often use short delays to fatten up the sound of many
instruments.
Couple of questions regarding the mic
setup for the guitars.
Firstly was it one cab per guitarist or was it a more involved setup?
Yes - but we changed the combinations of head and cab
to get the sound for each song.
how did you place the mics? what kind of distance from the cabinet was involved and how
did you balance and blend the two mics together from
a phase coherence perspective? did you adjust this
dependant on the song or to the extenet to which the
head cabinet combo was being driven volume wise?
I don't really know how to answer this! I combined my
experience with my instinct and used my ears to decide what worked. I honestly
am not trying to be a clever **** - that is the way I work! Obviously I avoided
phase cancellation and adjusted as required.
Did you start with one as your main picture and add some 'air' with the other
or did you opt for getting a wider tonal picture by having them both similar
distances from the cab and having them on different parts of the cone/cabinet?
Was the any degree that you offset the angle of the diaphraghm
to account or the amount of air pressure etc. just looking to get some idea of
what you were fishing for when you were micing them
up and if there were any hard and fast starting points outside of the 'touch and
tone' the Mal and Angus supply to getting the results you did?
Again it really isn't that complicated! I listened to
the sound of the guitar and found the best way to get that tone and power on to
tape. What I was fishing for was to capture what they did.
Apologies for the multi questons - It's pretty much
the best rock guitar sound ever committed to tape and I'd kick myself if I
didn't take the opportunity to ask!
No problem! I hope I have got you closer to the feel of
how I go about things and thank you so much for your kind words.
Tony

You know I'm not sure - one of the JH series?

guessed that. It sounds like an 1176 on 'smack'. Huh!
No compression on recording - sometimes a little on
the toms or overheads when mixing. Is an
1176 on 'smack' like a DBX on 'crack' [refeers
to the comment above]
Of course, I don't have a U47 for my kick, either....
Then a Beyer M380 is awesome!
Tony
What I really want to know how this album have such a amazinf
prescence and a great center!...if you listen
"You shook me all night long" what strikes me is the center...the
kick and snare are just in perfect center and the vocal right in the middle
///is scary ...sounds like brian is singing just here
in my face!! maybe sounds crazy...but how you make this amazing center...I did
not hear that often....
This has a lot to do with using the sound of the room
and mixing very gently and quietly - that way you can get the definition right.
making sure everything is in phase helps too and
ensuring that the signal path is as clean as you can get it.

hell that's a 57 on those guitars, must be an LDC or SDC". I was also
pretty convinced that was an AKG on the hihat. It's
cool to get some validation from the source!
A few more drum questions since they do sound so awesome:
a) Can you talk about the mixing on the overheads? It sounds, on Hell's Bells
in particular, like the cymbals are in another room from the rest of the drums.
Was that natural reverb from the room, or did you have the overheads going to a
send where they were high-passed and then verbed?
I can't say I had particularly noticed that!. There was no reverb on the overheads and i never high
pass cymbals as the main harmonics of cymbals are actually the lower
frequencies. I wonder if you are listening to a 're-mastered'
version which (in my opinion) is nothing like the original mastering?
b) Can you talk about how you got the kick and snare so isolated? In a nicely
live room it can be hard to, for instance, keep something like a U47 on kick
from picking up tons of stuff besides the kick. Same thing
with the KM86 on the snare. Was it just really good mic
placement or did you, for instance, use a blanket tunnel on the kick?
They are not really isolated as such - it's just that
the spill from one to the other has not been compromised by excessive EQ. I do
sometimes use a blanket tunnel on the kick and I have been know to create a
snare 'collar' to keep hi-hat out of the snare mic.
Generally though this is when either the kit is not well balanced acoustically
or the drummer does not have good dynamic control.
Thanks so much for being a part of such an awesome album, and for taking
questions!
My pleasure!

i used to fatten the snare with a sansamp

The irony of course is that whenever I have tried to
use it on contemporary recordings artists often say it's 'too 80s' !

don't want to do a $8000 experiment.
The head on the kick will have been a white coated. I quite like the thicker
Emperor heads.
The U47 is perfectly capable of taking the kick drum.
It is of course not inside! I always angle it slightly away too and use the pad
- the -6db is best but the -10db will help if it is a very loud drum.

I often find the world is divided with those who prefer
H to H and those who prefer B in B!
They were recorded in different ways. I didn't actually record H to H - it was
done in Roundhouse Studios which was very dead so there was no spill between
the instruments. As a result when I came to mix it I needed to create the
impression of the room and fed drums and guitars through speakers into Studio 2
at Basing Street.
I was quite pleased with the results but when I was asked to record B in B this
led me to make sure I had plenty of controlled spill to help blend the
instruments.
I'm not sure I would describe B in B as darker or H to H as warmer so I am not
sure what you mean? I think h to H is perhaps lighter than B in B?
The two microphone thing came about because I wanted to spread the guitars more
without pushing them too loud.
Thanks for the compliments!

Are there any other little tid-bits you could share
about the mixing of highway to hell? Any other
thoughts, insights, gear used.... Maybe what board it was mixed on? It doesn't
sound like there was a whole lot of compression used.
Thanks Tony,
D.
Well it was mixed on a Helios console which had some
F760 compressors built in but no not much compression used.
I really only had the EMT 140 plates, EMT DDL, tape delay, some Eventide gear,
1176. It was the same room and board where I mixed Catch A
Fire.
I used some Altec monitors to feed stuff back into
the studio and create more ambience.
Sorry - not much more to tell!
Tony
