I think the TS9 will be more likely to accomplish what you want hitting a tube preamp.
Try running one of your overdrives in the FX loop and one up front (and vice versa), or just see what kind of grit you can get out of your preamp and then run the Sansamp in the FX loop with a good bit of OD.
I find the Sansamp OD to be pretty smooth and fuzzy, maybe a dash poorly defined at high levels.
