Marbass superbooster does it. However I get a slightly glassy edge to my tone when just using the boost. It's not very prominent and helps lift you up in the bandmix, doesn't bother me much but it could be a thing.
Also they are discontinued, so secondhand or old shop supply is your only bet to get one.
Lastly, they run on 12v instead of the generic 9v.
I can rate it as a simple clean boost, and separate easy Tone control (has a second footswitch for this)
