Thanks Beepster!  I'll give this a try!

Cool. I'd love to know how it works out for you.
 
On a related note... I just got a chance to listen to some of the prelim work the fellow I made these tracks for did using a completely other sim/setup and they are still perfectly clean, clear and strong.
 
I'm looking forward to see how well it works on some high gain single coil blues stuff. I'm assuming it will work just as well but i MAY have to turn up the NoiseCancel faders ever so slightly.
 
The best part is now I can use my old MXR Micro Amp (simple gain pedal) to get a much stronger input signal to use with the sims. I've always been able to get some good quality blues sounds from TH2 but going line in either from the amps or direct through the interface kind of ruined the dynamic range so I could get a good punchy gain-y signal or a nice quieter clean signal but not both from the same sim setup. This, in theory, should get me more realistic response like one would get from a tube amp.
 
Of course the MXR pedal increased any hum already present thus stomping all over the sound. Now I should be able to completely yank it.
 
This may also make my old Korg AXFX multi processor pedal more useable for recording. It's got a really nice acoustic sim that works well with my hot rodded Pacifica. Very realistic but again it introduces hum. If I can make it work how I want then I won't have to worry about screwing with micing my actual acoustic all the time and all the problems that can arise from it.

I listened to all the tracks from the siession that the Yamaha THR10 was used on.  I can't find any hum, I remember I cleaned up the "quiet" parts of the tracks and the hum isn't apparent where there is actual guitar.  
 
I have a recording session scheduled Tuesday and I'll try to replicate the hum using the THR10 and then see if your procedure cleans it up.

Cool. Looking forward to your experiences with this.
 
Cheers.

Cool!

I would REALLY like to know how this works out for you, Geoff. I'm sure you have piles of live stuff this might help with. Perhaps DI stuff.
 
There are also other NoiseCancel settings in R-Mix that I intend to try on mic/room noise/hiss using this method. It's just a click to change the NC option in R-Mix.
 
Cheers.

Well, I was hoping to create some hum today, so I could try out the procedures but everything was clean.  Where I was getting some noise through the Yamaha THR10, today it was clean. 
 
I'll still work on getting some hum as I want to try the procedure. 
 
 

Hi, firebird. Thanks for the update. Try adding a really high gain amp sim preset on a track/clip you have recorded (like a Rectifier model set to the distortion channel and the gain cranked). That'll draw out the hum on pretty much any guitar signal. Then put this chain before the sim. Normally that type of thing would need gating for in between the performance. Once I applied this chain to the dry signal I could turn the gate on the sim all the way down and there was no noise at all. It was a little surprising actually.
 
However not having any hum on whatever your are working on sounds like a good problem to have. Wish my gear was that quiet. lol
 
Cheers.
