Ok, so I e-mailed Greg, & asked him if I could copy/paste/quote his response, & here's the answer....
I asked him "Would you care if I copy/pasted your thoughts on the Marshall Silver Jubilee" (basically what I asked anyway)...
Here's what the Gerg has to say:
"Sure. Lol. It's only IMO the most overrated, overhyped amp in Marshall's history. Unless of course you're an 80s shred wanker, then it's great, because that's the only sound it does. It's valuable for it's collectibility because an actual 87 Silver Jubilee is rare. It could be a good flip. It's tone is not "classic Marshall" if that's what he's after. It's all hype from the cork-sniffer nostalgia crowd....which is funny considering it has solid state clipping built in. I have tons of first hand experience with a true Jubilee. I can get it back here at my house tomorrow night. Give him my email address an tell him to email me if he has any questions. I saw that thread as a guest, and to see people chiming in with no experience has me face palming."
So, pikingrin, if you're interested in Greg's e-mail, shoot me a pm & I'll send it to you. He can probably answer more questions you may have about the amp than anyone I know....He's actually helped me with quite a few gear purchases, & IMHO, he'd never steer anyone wrong...
