@Kenneth, thanks for the LePou suggestion.

@joakes, envy your many ins/outs. With my limited outs on the Quad Capture, my hope is if the DR880 allows me to split a clean signal to one side of the stereo (for DAW) and another with effects to the amp.

You really should open TH2... and watch Cake's videos... with TH2, you can play with the "mic placement" in front of the amp model you're using.  Moving the mics can reduce alot of the amps natural, modeled noise.

Best,
Rob

Hey - on the whole guitar noise thing - which I HATE as a keyboard player with delicate ears :) 

I have a question.

I know that for recording real amplified signal that to get rid of the noise I can record a dummy track of just that noise, and then invert the phase - which should cancel out the noise frequencies on the 'real' guitar track, leaving pure niceness for guitar tone.

How would I do that working with after the fact processing, such as by GR5 or any of these other amp modelers?

I LIKE a lot of the sounds, but really do not care for all the noise.

Thanks for any thoughts on this, AND thanks to all who have posted free VST plugins for this thread.  I will try them out,

ok well this is what I have done. You are on the right path as far as recording another track of just the noise. but to get better results both tracks need to be in stereo. Then you invert the phase on one of the tracks. If you are running two stereo signals through two different buses. for example one for the guitar noise and one for the guitar you can use the channel tools to invert the phase. This also works on effects with the same settings.

You would use buses if you had 2 or more guitar tracks that require a distortion sound. be sure and group the fader of the guitar with the fader of the other track with just noise So when you adjust the guitar volume you adjust the noise level as well. It has been my experience that the tracks need to be in stereo in order to get better results. at least when I have tried this it seemed to work that way.

inverting the phase with two duplicate tracks is also fun to try on effects in addition to being a good tip for noise reduction

Thanks, but I am still a bit confused - just new to this side of things - coming from keyboard side of things.

OK - since the GR5 tone is coming from is as an effect, and not actually recorded until I am mixing it down, I do not have a duumy track of recorded noise yet.  

Would I create such a dummy track by mixing down an empty track through the GR5 patch I am using?  And THEN do the phase inversion thing?

I like the part about grouping the faders - Got to go watch that skydiver guy - he's about to jump.

I'll check back in a few minutes.  THANKS!

Well I have only done this with audio tracks. I have not used midi with phase reversal. but try this and see if it works. let us know if it does the job

1. make and save the crunch preset you want to use in GR

2.create an audio track and arm it to record in stereo. You don't need to plug any thing in we just need a blank clip. 

3. Press record and record a blank clip with no audio signal.

4. once this is done click on the effects bin for the clip and insert GR. Then call up your preset.

5. Bounce to clips the effect. You should now have your track of empty noise. Remember to group the faders

6. Reverse the phase the phase on that audio track and see if it cancels out the noise on your midi track. (which should also be in stereo)

If this does not work it may be that the midi track needs to be made an audio clip. You may be able to bypass some of the steps above. You might be able to insert the audio effect in the tracks bin instead of doing the bounce to clips thing. This will take up more system resources. you may not need the audio clip at all. you may produce the empty noise track without any clips being there. I don't know what approach will work the best. The ultimate thing to do would be to test every possible configuration of the above scenario to see what works best.

I did not mean to imply any need for doing such a thing on a midi track.

All I was trying to say was that I am a keyboard player - all of us keyboard players led sheltered lives, as far as dealing with guitar noise went, other than having to listen to guitar players :)

You confirmed what I was thinking - that a simple bounce of the track with the desired GR5 preset, then inverting phase. 

I will not forget to group the faders - THANKS!!

Oh, and ROCKY?  I think you might want to look replacing the tape with something like nippy clamps.  You sound a bit twisted - bless your heart :)

Sorry bob I guess I misunderstood. maybe that stuff will help somebody else reading the thread.

I used to just take use my MT-2 through my Line 6 head (two XLR outs for the two channels available) and send that to my interface. I was obviously recording the distorted signal but it worked reasonably well.

Not as well as TH2 is though.

I often use the CW amp sim.  Sometimes more than one instance.

EQ before and after, modulator, compressor, impulse reverb,..

Sometimes 2 buses with amp sim in both,...

It is very versatile. And easy to use.

I start with splitting the guitar signal with a DI, record the clean signal, and then record the stereo out of an epiphone amp with lots of variables for the 2 channels, and some chorus.

Also got a '54 gibson amp. The guitar into a ''71 wah-wah/booster pedal, into the gibson, way loud in the basement, gives a great moody blues tone.

Sometimes use the re-amp box, for guitar and other instruments.

But, internally, the CW Amp Sim is my little friend.
