I have 2 on my board, Ibanez ts9 and ts808 reissue. I use the 808 for my standard OD and the ts9 for really overdriven stuff. when used together it is a loud dirty oversaturated sound. My bandmates call it the koolaid tone, cuz it sounds sweet, like koolaid with about 2 pounds of sugar!!!! I also have a blues driver, really nice tones, I use that sparingly when I'm jamming by myself or playing an acoustic set. I really dig the tone of the boss paired with my acoustasonic and a boss ch1. I really havent looked into trying any others cuz these just seem to fit like a worn in pair of boxers!
