So this was partially a loaded question, and I posed it vaguely initially to see the responses. Thanks all for the feedback!
To JimmyM's point, I agree, no amp is gonna be a 100% clean representation, and in any situation you have to adjust EQ to the room and situation.
I was thinking more in terms of Scott Feldstein's interpretation, that he likes his amp/cab sound to be the same as his DI sound (ie, the amp/cab just "amplifies" the sound its given, not changes it.)
Duke21 straight up said, he loves the classic Ampeg and Marshall tones. We all know those tones, this is the "color" I speak of.
To Joe Louvar, for examples of clean amps, I'm talking about the givings of Markbass or Carvin which are generally thought of as "clean". But to others those amps sound "shiny" or too bright/hi-fi. I guess that clear hi-fi 80's tone is what I'm getting at when I say "clean".
Jim Nazium's comment is good, he prefers as clean as possible amp/cab, and no effects... this would be the most accurate representation of the sound that your bass makes. I'd bet he likes to play fancy basses!
What drove this question, is chaosMK's point, that the SVT 3Pro has too much influence in my tone. I'm a pedal junkie, and my basses are all polar opposites of each other, so I want that really different sound out of each configuration, and sending the sound to an amp that will more clearly represent what I'm sending it without adding too much flavor of its own. It was fun for awhile, but now getting tiring to have to adjust the EQ across my bass, VT Bass, and amp, then if theres a fuzz or other pedal engaged, adjusting the mids and EQ of those as well. You may say to ditch the VT, but the Character knob hits the high mid freq. that I spent years trying to dial in... I'd keep it just for that feature alone. Point is, various EQ's competing with each other and stomping each other out... and I can spend an hour honing them in at home, take it to a band situation, or a live room, and its back to the drawing board.
If I went straight bass -> amp, then I'd be looking for the best sounding / unique and characterized amp I could find. I realize now that when I want SVT, I can twist a knob on my VT Bass and be there, but for the rest of time I don't want SVT, I can adjust my VT to taste (or turn it off.)
I'm not knocking the 3Pro, its served me well over the last couple years. But I found I never use the tubeyness of it (always have Tube Power maxed out for clarity) and it just doesn't have the brightness/crispness I'm looking for. So I bought this Carvin B800 to try out... gonna keep the 3Pro for awhile in case I'm off base, but it will likely hit the chopping block as on paper, the Carvin serves my needs much better. Of course I'm running through an Ampeg HE 4x10 cab, and that may really be the crux of the issue.
Oddly I dig the tone of my 3Pro through a cheap Acoustic 4x10 more than through the Ampeg 4x10. Neither cab sounds as good to my ears as the first amp I ever had, a Peavey 300 combo with a big 15" Black Widow speaker... if I found a deep 2x15 Peavey cab, I think it'd replace both my 4x10's instantly. Thats why I'm keeping the 3Pro for awhile, when I find the cab that suit my needs, going to give it a fair comparison against the Carvin... if my issue is just the cab, then I'll keep both amps. But if the 3Pro is truly too dark for my tastes, I'll have to sacrifice it.
However, now that its getting warm again, I might pursue fEARfuls as I've wanted to for a long time, based on hype alone. My father used to build cabs for hi-fi home systems as a hobby, and is a carpenter by trade, but he's got the same problem as me of starting epic projects and leaving them half-completed, so would take some serious motivation between the two of us to get them finished.
Interestingly the poll results are near equal, with alot of Carrots choices.... you guys must really like your veggies!
