I agree with Kim about all the tangents that can be found in a thread like this one. I myself have been going over a lot of early threads that are no longer active in the Forum, trying to find specific information and have read about a lot of different things other than what I was looking for, but it makes for some interesting reading.
I just believe that when we take some of these classic songs into account and want to try to reproduce the sounds we are hearing for our own guitars, that in addition to the old vintage amps and guitars we are hearing, it's equally important to consider how that equipment was recorded too.
Let's take "All Along The Watchtower" for an example. Richard's version, which is a very good rendition BTW, is a live version vs. the studio version recorded by Jimi Hendrix. You can hear Richard's guitar is much hotter than Jimi's guitar tones, but that is because Richard is emulating the lush rhythm tracks that Jimi put down using layers of clean guitars with a tape delay. There is an acoustic guitar track with two clean electric guitar tracks, that while they are clean individually, collectively, they produce a slightly overdriven sound that leaves the listener with the perception that it is one HUGE guitar on the rhythm track. It's really three different guitars Jimi used. A cheap acoustic, a clean Stratocaster, and a left handed Acoustic Black Widow, ( I wonder what became of those guitars). The solos Jimi tracked two guitars there as well, one with his Strat, the other with a Gibson Flying V, and both through his Dallas Arbiter Fuzz Face. All of this was recorded with old condenser mics and tube mic preamps, with tube compressors, and tube EQ's through tube circuit mixing consoles and onto 2" tape. Back in the day, that was all state of the art, but today, that's dinosaur technology.
We are all very lucky to have grown up at the time we did, because we listened to all these great recordings, and they inspired us to get into music, because we all wanted to sound like that. Our ADA gear gives us the ability to get closer to getting that kind of sound for ourselves that we can't do with anything else. Instead of needing a warehouse full of equipment, we can use our gear with a laptop, and a few good quality mics, and get closer to that kind of soundscape, than we could if we used more modern amps that are available now. IMHO, our ADA gear is the bridge between the old and the new, and we can go from the vintage sounds all the way to the current guitar tones with a step of a button.
Sinn, if you set up the right environment in your DAW, and track multi layers of guitars of different types, you could very realistically achieve this kind of soundscape, or at least get very close to it. I don't believe you need to invest in a Two Notes Torpedo or anything like that, but a good speaker cab and a couple of good mic's can get you surprisingly close. It doesn't have to be a 4x12 cab either. A 1x12 with a removable back can give you a lot of options with mic placement and mixing, driven with a low powered amp. Micing the cab on a hard floor vs. on a carpeted floor also makes a big difference. These are just a few suggestions that are much more economical than investing in expensive processing gear.
