====Marshall JCM800====

Taken from [http://www.fractalaudio.com/forum/viewtopic.php?f=11&t=11801 Scott Peterson's thread]  on the Fractal Audio Systems forum:

I am a JCM800 guy. No matter what I am doing, it's always my base tone in 99.999% of what I do it ends up. :D I came of age in the 80's, it's where I come from. You either had a JCM800, or you played an amp that sounded like one. It was the base tone machine of the day in the music I grew up on. The JCM800 in the Axe-FX has always been go-to; from V3.xx firmware onward for me. Folks seem to like my take on it, so in the spirit of sharing and community I'll detail out my preset that I've completely built back up from scratch with V9.x firmware. '''These are the settings that deviate from stock (or are stock); anything not detailed out are default values:'''

=====An Additional Note From Scott=====
When running FRFR, the IR you use is as important as the your cab/speaker is for your amp in the analog world. It's a MASSIVE component of your end tone/sound and cannot be overlooked. To get the sound I was after I tried to capture a mix of close and far mic'd cabs/speakers:


The Cab block: Mix of Red Wire IR's<br>
*Mic: None, Drive: 0.00, Air Freq: 3623, Air Mix: 5.1%


Red Wire "Tone Recipe":
*Marshall1960A-G12Ms-KM84-Room-R.wav, 20% of mix<br>
*Marshall1960A-G12Ms-KM84-Room-L.wav, 20% of mix<br>
*Marshall1960A-G12Ms-R121-Cone-6in.wav, 40% of mix<br>
*Marshall1960A-G12Ms-D6-BackCab-0in.wav, 10% of mix<br>
*CelestionBlue12-KM84-Room-L.wav, 5% of mix<br>
*CelestionBlue12-KM84-Room-R.wav, 5% of mix<br>
