Hi,
i've uploaded a profile of a Marshall Kerry King Signature JCM800. I used a Beta 57 and a Sennheiser e609 blackface. Cab was my ENGL 4x12 loaded with V30 Speakers.
Use an EMG 81 equipped axe and you enter SLAYER territory. I added a post stack EQ to give it some more bite, disable it and you got the raw profile.
Check it out and shout back at me what you think about it.
Cheers
Helge
