I've had my reissue TS9 for years. I have tried to love it -- what guitar player whose tone I love has not used this pedal? I've used it through an SF Twin Reverb, a Crate VC5310, an SF Champ, and now and Excelsior. I haven't found anyway to dial in a tone I like. It seems like it takes away all the bottom end and sounds like I'm playing through a 6" speaker. I guess it's just not for me. I like the sound of my Champ and my Excelsior when they are just cranked up for natural overdrive. I can't get an overdrive sound with this pedal that I like at low volumes. Seems like everyone loves the Tube Screamers except me. I'm going to Ebay it (or maybe put it up here) and start searching for something different. I also have a VS Jekyll & Hyde but it's a bit more complicated than I like, although it is nice that it has some tone control to make up for the lack of it on the Excelsior.
