I have that pack, its very authentic....what is interesting, and I noticed this more on a Ozzy pack, that the raw sounds aren't great. In other words they are authentic but didn't realise how thin sounding Randy Rhoads guitar sound was, but it sits well in the mix...
Made me realise:
1) Its more about the band mix than the guitar sound on its own...I did know this but hadn't really seen it in the flesh
2) Some of the tones of old are perhaps not as great as we remember ( rose tinted specs???)
3) despite download these great profiles, I still sound crap
