Question about Darkglass AO ultra

Has anybody put a booster in front of it?

Like a guitarist would put a TS or sone infront of their gain to get more drive?

I like what the AOu does for me. I run it to put a touch or two of drive. Iv never liked its full on distortion though. Sound too lose and flubby for me.
I was considering:
A: get another distortion to run when I need it.
B: try a booster of some type to tighten up the higher drive...but I dont kniw if thsts doable.

Any recomendations?

I also tried an X ultra over last weekend, I like it for the same use as I am using the AO but higher gain on it just gets too hissy and clanky.

Ultimatly along with the low gain normal tone I wanted a nice high gain, focused, more saturated.

Any incites?
