I would essentially like to turn my Archon into a 3 channel amp. Clean, Crunch, Full amp saturation.
First, any overdrive pedal can accomplish that. So it’s a small part of the equation. And any overdrive can go from semi-clean cruch to harder overdrive, so the question remains; what do you like?
You’re simply going to have to play a bunch of them to get a feel for this.
There’s crunch, and then there’s crunch. Example: the Klon style pedals are way different types than, say, the Shiba drive, which is both more saturated/sustainy and has a different ‘grain’ (for want of a better term). There are pedals that do “soft” clipping, pedals that do “hard clipping” (these are not hard rock vs soft rock, it has to do with how the pedal shapes the transient at the note attack). And there are pedals that do more than one kind of thing, from choosing between transistor types to having both a boost and OD on the same pedal, to digital stuff (digital ODs never have worked for me but lots of players dig them).
The Tube Screamer types are far more midrange focused than some of the others you’re looking at as well. That can be awesome, or not, and it very much depends on what you’re thinking about achieving, Some pedals are very tranparent, some color the tone quite a bit, but that can also be a good thing.
Some pedals compress a lot, some don’t.
Also, certain OD pedals sound best with some amps and not others, and to make things even more confusing, setting up pedal, guitar snd amp usually matter quite a lot.
You’re probably getting the idea that this is all very personal, and it is. Also, that pedal whose tone you love in a clip may or may not work for the way you play, how hard you pick, your guitar, etc.
If it’s your first OD pedal, ever, you might want to go to a brick and mortar store and familiarize yourself with how certain generic pedal types generally work for you. By that I mean play a TS type, play a DS-1 type, play something like a Klon or a Klone, try a few other boutique models, and see what floats your boat.
It might turn out that you’d want more than one type for various purposes.
What I’d suggest is listening to clips or internet “experts” only as guides to what you might be interested in trying. There are no rules, there is no “best,” and ultimately each of us is on a very individual tone quest.
