Hey Vastman,
I'm sure you'll enjoy shreddage 2.
Do you have the MusicLab stuff ?.
I tend to use RealLPC a lot, it's got awesome control/articulations - I have shreddage 2 and a whole bunch of other virtual guitars, and each one has their strengths and weaknesses.
On the SL front, I would have thought it was up to MF to sort that out if you bought it from MF.
SL would not have any reference or info. I've always found SL very good when I've purchased from them.
MF on the other hand, just gave me the giant run around with a Mic set that said "Ships Internationally", but at checkout refused to ship to my country. Live chat, followed by 4 Support tickets and 3 phone calls, and quite frankly my tome is worth more than I saved. And it was nothing less than a comedy of answers from them.
Their last and final answer was - It's an error on the site, doesn't ship to your country sorry ... and this was after they sold it to me over the phone. I see it does ship to my country, I've received the shipping notification :-)
I'm sure you'll enjoy ImpactSoundworks stuff, I couldn't afford the everything bundle at the time I bought over there, but grabbed Shreddage 2 and Juggernaut, awesome stuff !.
Take care and enjoy :-)
Cheers - Cliff
