I played a friends original TS-808 back in 1983. It didn't do anything for me at the time. I have a TS-9DX now. I like the mode options. Could be smoother and more natural (can be a little brittle sounding, though there's a tone on there that solves that reasonably well.). TS's really need a good amp to drive. IME if the amp is stellar sounding to start with, a TS9 can squeeze out that last 3-5% of sensitivity, drive and tone. My preferred boost/drive pedals these days, however, are not a TS-type, but the Archer Ikon and the Brain May Treble Booster Classic, which has all 3 models of Fryer boosters in one housing. I want to try the Jeff Beck version of the Ikon, but kind of expensive just to try out. I don't use boosts a lot, so I have limited experience and don't have enough of a need to obsess over them. They're just a useful tool once in a while, often I use them just to balance the level and drive when I need to switch between a Gibson and a Fender in the same backline.
