    ok i m micing a 4x12 cab with a sm57 micing the center of the cone, and read that a u87 at the edge of the cone is quiet good for taking low end as a second mic, but there is my question how far from the cab do i put the u87, in which direction, what type of capture do i choose ? ( cardio, omni...), cuz i ve put it at the same distance as the sm57 ( like 3 inchs from the grill ) and the capsule is saturating and the sound is reallllllly bad :), the sm57 is perfect but the u87 is non good placed i think.
    Please give me some advices thx ;)

    There are a lot of session photos with detailed descriptions of miking cabinets at http://www.royerlabs.com of course involving Royers... but good tips anyway. A lot of the setups involves blending a SM57 with a Royer ribbon and a large D condenser. I´ve tried a couple of the described techinques with excellent results.

    wow this is really a good reference one !
    but all those mics seems to be very close to the grill, my u87 is so saturating even with the -10db on, why that ? is the amp too loud or ?

    Back up the u87 to taste. Don't worry about the phase coherence of the mics right now when you blend them - if you are going to 2 separate tracks (1 for each mic) you can fix it later by sliding one to match the other. Try putting the u87 6 inches or even 9 off the grill, on axis with the edge of the cone. Beware though, listen to the u87 soloed and if there is phase coming on the way in without that second mic there is no way to fix that. Move the u87 around while having it soloed until you get the desired sound you want. Then leave it there and record both mics. Move the u87 forward in time to meet up with the sm57 mic and you should be there.
  5. tone?

    what sort of tone are you looking for?? I had a session a few months back and used the EXACT SAME setup as you: 57 and U87...

    i was looking for a heavy, crunch tone... I was micing a Marshall 4X12 (with an all tube head). the biggest thing i found to work was this:

    TAKE OFF THE BACK PLATE TO THE CAB. I did that and everything changed... there was no more mud, just pure tone... the back wall gives you the late bass womps in your signal. I took that off and miced the top 2 speakers...

    57 was pointed right at the cone on a 45degree angle and as close as i could get it to the grill without touching.
    the U87 was pointed right at the cone about 4 to 6 inches away from it... strait on.

    if you want to listen to tones... you can check out the band i was recording:

    you can download some songs... i also posted full production notes on there from the session.

    I would certainly worry about phase before you start recording. Simply moving a track in time will not guarantee complete phase coherency. You need to move the U87 around until the phase sounds correct.

    ok it may be the dumbiest question ever
    when i solo the u87 to hear if phase is coming...well how can i hear the phase prob...if its soloed...ok ok dumb question...but i need to know that if i want to be aware of that phaaaase ;)

    Btw i put the u87 like 2feet away and still have nasty clipping from the capsule... ill definitly see for a line attenuator.

    You can't hear the phase issue with one mic solo'd. The whole idea is to sum the mics panned straight up and listen to the sound.

    If it sounds hollow or phasey, then go out and move the mics aropund a bit and listen again. There are other ways to make this go faster but start by listening closely.
