JK - Aw, hell - how far off-topic should I go here in fair reply? I'll assume I've got your invitation. I've stated up-front that a "rubbish" sound is highly subjective and that I wouldn't argue if you get results with instruments that make me unhappy. Also, I cannot agree more with Vavoom's "tone starts in the hands". Amen brother.
But ...
I do feel that modern guitars are not the best - some are, many are not. How can a 2011 Gibson Les Paul sound like its ancestors if it's drilled full of swiss-cheese holes for weight relief? Look at an X-ray of modern LPs. Got to change tone away from that which made it famous. Why does it happen? To make the damn things lighter for those standing up for three sets a night. Not a tone choice. Changes the bottom end and there's no way of the fingers getting that back. I fiddled with the VM for an age wondering where the hell to get those frequencies before I bought a 1978 Les Paul Custom. Yep, there they are. This is not subjective - it's just a physical fact (but which you prefer is up to you).
The PRS looked gorgeous (not why I bought it), very well made, easy to play, lots of sustain. It's over-brightness started to grind on me - it seemed to trade on icepick high-mids to get its characteristic chime unplugged that was thin through an amp. Was much better through a Mesa but did not like Marshalls that I've learned to prefer. Look at most PRS name players and see the amp choice (Santana, nu-metal etc.).
The Custom Shop Strat - worked for clean, just crapped out for rich distortion. Would work for some genres but never in a million years for the stuff we discuss round here. I think the CS label is highly questionable - it's not a custom instrument in a way that anyone understands the term. That's not to say that the CS produces anything other than fine products but they're not hand-crafted by Master Builders - we, the public, are just being charged a label premium to get the wood and other marks of quality that used to be standard priced (see also Gibson's 59 RI LPs). Great marketing device for selling what used to be a £1.5k guitar for £3k.
What works for me? A 1978 Les Paul Custom (£2k for the real article, £3.5-4k for the modern Custom Shop 70s John Sykes or Randy Rhoads reproduction), a 1982 "Dan Smith" Fender Stratocaster (£800 ebay impulse buy - half a modern Strat equivalent price). And a modern guitar I think sounds great (huzzah!) a limited edition 52 AVRI Fender Telecaster (near as dammit same as listed by Vavoom but thin-skinned and modern neck radius - straight swap for the PRS). So not opulently expensive preferences from me. I would pay any price for the sound I want.
In a tone contest (I know how unscientific that would be) it was not just I that went with these as being "better" (i.e full-bodied, rich, whatever adjective helps - more like a classic rock recordings with no ingenuity required from me) - it was everyone I knew from full-time pros to my (non-playing) wife. And it's a plug-and-go difference.
This is w-a-a-y-y off-topic but I believe it is what you wanted. My subjective preferences are based on music frequency facts drawn from classic recordings but I wouldn't dream of negating that which works for others with different ears, hands and hearts. My original post was, I think, relevant to getting immediate joy from the VM.
Vavoom - we have the same guitar so I hope the following helps.
52 Tele >>> VM LDR >>> Master Vol 10 >>> Detail 4-5/Body 1-2 >>> Mid-boost in or out >>> tonestack all at 5 (except Bass at 2-ish).
Put it in HDR for more of a Led Zep II vibe (I mean vibe, not a forensically perfect repro). Master Vol 5+. Keep pedals mostly the hell out of the way.
If that doesn't work for you then we do not share the same taste in sound and I respect your difference of opinion.
