This isn't a bitching thread, it's about getting 70s sounds.
RG: If you want 70s sounds, the most obvious thing is to play 70s style and use 70s gear, as much as you can anyway. You can help things with the right kind of processing - listen to the EQ on those old tracks, the balance of sounds, the way they used dynamics...
One problem with buying 70s kit is that collectors are bound to sprinkle it all with copious amounts of perceived mojo, and prices become prohibitive. Depends what you want.
If it's effects you want, try things like the EHX Small Stone (classic chassis) and MXR Phase 100, though I recently picked up a Boss PH-1r and that's a nice one. Also try the Electric Mistress for flanging, cheap old digital delays (the Digitech RDS1900 is a good example) and some kind of BBD-based delay (though vintage units can be pricey). The DOD FX90 is supposed to be good for cheap, but even one of the Behringer units would get you started. The Boss CE-1 is a classic chorus, but you'll find the CE-2 cheaper. Early CE-2s go for sturdy money though. Get a later one, they sound the same. I know most of these aren't 70s originals, or even 70s effects, but I've had useful results from this kind of approach.
One other trick is to run things through an old cheap mixer. I have a couple of late-70s mixers that do good things to the sound - ie., they ruin it, technically speaking - they have 2-band EQ, switched gain controls, noise - and a pleasing sound. That, with careful use of compression.
In terms of synths and patches, you'll be looking at VCO machines mostly, and divide-down stringers, organs, EPs... pick a 70s synth, look at its architecture and mimic it as best you can with what you have. Wherever you can introduce instability or random fluctuation into pitch, for example, on a VA, do so. You might be surprised how well it works.
Many 70s synths will be collectors' items, but there are also bargains to be had if you're lucky. I'm thinking of mono-presets like the Teisco S-100P, which is a great synth for almost no money, but don't come up often. Or the Crumar Multiman, etc. I mean, if you're on a budget you probably won't be getting a Mini, Rhodes, CP70, Hammond and Mellotron. But you coud feasibly mimic somebody like Trobbing Gristle or John Foxx, etc. who used a limited range of more easily replicable synths (ARP Oddy, Roland System 100, etc). Even the SH-09 is still relatively affordable, maybe even the Rogue.
Modern synths that sound like they have 70s blood in them are also available new. The Moog LP is one example - I've heard good things about others too; you should probably look at stuff like the Vermona Lancet or some modular kit.
Then you've got the fact it was all recorded to tape. That in itself is a whole other world of pain I suspect. Good luck.
EDIT: I've just seen your gearlist. SH-1000? Multiman? What are you whining about? Multitrack your SH-1000, run your Crumar through a Small Stone, and pretend you're JMJ. Done.
