    A friend of mine brought over some recorded tracks of guitar work that needed some limiting via my Manely Vari Mu,,no problem,,I thought--right?
    AS I listened to the tracks,I noticed that the over all sound of the lead guitar tracks sounded nasal,,so I asked him how he went about recording the tracks,,keeping in mind that the tracks souned good,but,had a nasal issue.
    He used 3 channels.1 guitar signal split going to amp/modeler.
    1 channel used to mic a tube combo amp. Panned straight up
    1 channel , from a guitar modeler (DI) Panned hard left.
    1 channel , from the same modeler (DI) panned hard right.
    The channels that have the modeler, sound great,(in stereo) but when you blend the channel that has the miced up combo,the nasal (phase?) issue comes into affect.
    If you listen to the channel that has the miced amp by itself,you can defently hear the nasalness
    Heres my question,what freqs should I be looking at,to try to rid that one channel of the phase issue?
    All channels have the eq set flat.

    If you are listening to the single microphone on the Cabinet, by it self and it sounds "nasal", then that is the sound the speaker probably made and not a phase issue. If the modeler sounds better than the Cabinet, don't use the Cabinet. "Doctor, it hurts when I do this." "So don't do that."

    You might want to try to suck some of the midrange frequencies out until the nasal sound is reduced? What frequency? I don't know because I can't hear it. Only you can. So if you have a sweepable equalizer, first boost it up all the way. Then start to sweep the frequency across its full range. When the nasal sound is accentuated, then turn the boost all the way down to full cut. If it still sounds like crap, try a different cabinet and microphone combination and go for take 2. So are you trying to add the processing to each individual channel of guitar or as a complete stereo pass?? Adding compression won't improve bad sound or poor recording technique as you have already discovered. Only good sound recording can be improved through use of dynamics processing.

    The DI signals are probably coming through faster than the mic signal. So to combat the phase issues that result, either your guy would have needed to check this issue and move the mic to get the most acceptable tone out of the setup with all signals running (maybe he did and the nasalness is intentional?), or do what I sometimes do--scoot the DI tracks back a little bit in your DAW to make them line up with the mic'd track.

    I wish I could record the miced track again,but no can do,Im gonna try to find the mid freq range and try to at least make it sound not so nasal,Im trying to clean it up before I limit.
    As far as added process to each individual channels,,no,,
    THe other two channels that have the di signal sound pretty damm good if I say so my self.
    Its the miced cab that sounds like someone pinched the nose on the speaker at the amp.

    Ive tried pulling the level down a notch on that track,but it loses the full body of the guitar tone.
    Man what I would give to have a Manely Pultec right about now :!:

    I'm not talking about level. I'm talking about scooting it time-wise. You will probably want to scoot both DI tracks the exact same amount, since they were both recorded the same way. Scoot them back until the waveforms match up with the mic'd track, or until you like the way it sounds.

    Thnks for the advice,I found the problem last night,just had to take the time to find the mid freq that was giving me the problems and cut.
