I'll add the Voodoo Labs Sparkle Drive to the list. It has both blend and EQ. As a side "benefit" for you, once you set the blend to around 50/50 or so, the pedal is fairly subtle even at high gain levels.
This is what I use for this purpose. But do note this is sort of a holy grail here on the effects forum- you'll see *a lot* of these kinds of threads if you do a search.
What I take away from that is that there is no one-size-fits-all solution for this problem. Differences in basses, amps, and personal preference just mean you'll have to hunt around a bit. But I would give up any Muff or muff clones for this purpose, just my opinion to help thin the search field. Good luck!
