No, or rather it sounds TSish in normal mode with the tones flat, but the twin tone controls mean that you can (very quickly) voice it how you like, either to suit your guitar or amp, or becasue the ridiculous mid hump of a TS is annoying
In the Modified mode it's less humpy, little more bassy but in a good way, and more gain - basically a really good soloing push (in to my amp anyway)
Better than the TSs I've tried in every way (althoguh I usually don't fall for the vanilla TS any way, better than the modded BD-2s (multiple) I've tried (and I really liked one of those) and has all those nifty Hardwire range features that I think are good.
Obviously it's not for everyone or I'd not have been able to get one used like I did, but I think these are staggeringly good pedals and not something I've heard much about. After I tried one and loved it I kept schtum so I didn't scupper the chances of picking up the next used one
